General notes

Improper handling of the product may result in damage to the product or property.

Mount the product on a soft and clean surface. If necessary, place a blanket or similar underneath so that the surfaces are not scratched or damaged.
When mounting the product, proceed carefully and follow the mounting instructions.
The product has considerable weight. Carry out transport and assembly with at least 2 people to avoid damage.
Before you start assembling, check the solar module, the inverter and all cables for visual damage.
Do not stand on the module or the module frame. To prevent grease stains on the module, avoid contact with your hands on the glass surface and ideally wear work gloves.
Write down the model and serial number of the components [inverter, solar module] and keep the numbers. In the event of a defect, we need the numbers for clear identification.

Leg mounting

Tools are needed: 1x Allen key 3mm and 1x Allen key 5mm

Lay the table with the solar module flat on clean surface. Best is to use some protection like a blanket or cardboard in the size of the module underneath. Be careful not to damage the glass front.
Take one of the four legs and slide it on to the first corner of the table
Tighten all 4 screws.
Repeat above steps with the other 3 legs.
The leg with the clips for the connection cable needs to be installed like in the picture below, next to the micro inverter.

Connection cable routing/mounting

All the cables are pre-connected. Normally you are not intended to make any further connections. Just check before plugging in the plug to the power socket if all connections are done and tight. Only connection you need to do is to plug in the connection cable from the micro inverter into the power socket.

Mounting the connection cable to the leg

One leg is preinstalled with clip holders for the connection cable. The picture on the right shows the finish mounted connection cable. Attach the connection cable like shown on the right.

Connecting the micro inverter

The micro inverter is already pre-installed to the frame of the table in this set. (It may only be necessary to connect the solar modules (DC) to the micro inverter.) On the AC side, only the connection with the enclosed connection cable must be made. A Wieland plug connection is recommended here according to VDE. A Schuko/Type13 plug connection with a Schuko/Type13 socket is also possible because the used micro inverter is a proofed for VDE 4105!

CAUTION!
Observe all local regulations and restrictions before/during installation.
CAUTION!
The external protective grounding conductor is connected to the protective grounding conductor terminal of the micro inverter via AC connection. When connecting, connect the AC terminal first to ensure grounding of the micro inverter. Then connect the DC terminals. When disconnecting, disconnect the AC first by opening the branch circuit breaker but keeping the protective grounding conductor in the branch circuit breaker connected to the micro inverter. Then disconnect the DC inputs.
CAUTION!
Install disconnect devices on the AC side of the micro inverter.
CAUTION!
It is strongly recommended to install surge protectors in the appropriate meter box.

Connect the solar panels (DC connection)

Connect the solar panels DC cables to the DC input side of the micro inverter. The 400W inverter is already connected to the solar panel via MC4 connectors. Simply connect the DC connection cables of the micro inverter to the matching counterpart of the solar panel. When doing so, plug the pair of connectors together until you hear a “click” sound. The connectors of some solar panels have the polarity (+, -) printed on them, which is valid for the panels. The DC cable of the micro inverter with the plus marking (+) is connected to the – pole of the panel, the negative marked cable (-) to the + pole. Make sure that the polarity is correct. Note: When plugging in the DC cables, if the AC cable is already plugged in, the micro inverter LED should immediately flash green and start synchronizing with the grid within 2 minutes. If the AC cable is not plugged in, the red LED will flash continuously and repeat this until the AC cable is plugged in (see chapter LED Status). Connecting the micro inverter to the AC grid (AC connection) A maximum of 1x 400W may be connected to an EU / 50Hz / 230V installation with 13A automatic circuit breaker. The connection to the mains is made with a suitable power cable. Only use 3-core cables that are also approved for outdoor installation and have a conductor cross-section adapted to the amperage (preferably 1.5mm² or 4mm²). Fasten the connection cables to the mounting rail using UV-stable cable ties in such a way that the cables are protected from rain and sun and, in particular, the plug connections cannot lie in a puddle of water. To connect the micro inverter and the connection cable, the pre-assembled AC plug-in system in combination with an AC cable and assembled BC05 connection socket or the AC string input/output can be used, depending on the delivery variant. To mount a Wieland connector, the pre-assembled BC05 connector system must be removed.
Note: Other plug connections / systems may be possible, provided they are suitable for outdoor use and the current levels involved.

Set up the table

After assembling the table checking all the cable connections you are ready. Make sure the locking screws of the telescope arm are tight. Now be at least 2 persons to lift the table up and turn it around and put it on its feed.

Important:

Depending on the location of the table, it is necessary to supervise or fix the elevated power plant to prevent damages and accidents.
When the table is used as a table, disconnect the Micro Inverter.
Use coasters or a tablecloth when placing cups, plates, cutlery, pots, etc. on the table. To prevent scratches or defects of the solar panel.
Make sure that the connection cable to the power socket does not pose a trip hazard. If possible, lay the cable in a straight line and directly to the nearest wall with power socket.

Leg height adjustment / Level out unevenness

Tools are needed: 1x 14mm open end wrench

To adjust the height of the table rotate the bottom nut of the table foot counter clockwise. Note: The whole table foot will turn.
Important: Do not unscrew the table foot further then 20mm in height to assure the stability of the table!
Rotate the nut until either the wanted height is reached or the unevenness is balanced.
Now tighten die upper nut to lock the table foot. Screw it clockwise until the nut reaches the table leg.
Repeat step 1-3 for the other 3 legs if necessary to reach the wanted height or balance the table.
Tip: Use a spirit level to check that the table surface is leveled

Angle adjustment

You can choose between 3 different angles to set up the solar panel. 20°, 30° and 35°.

Estimated yield

The mounting angle (20°, 30°, 35°), the orientation (west, south, east) and the geographical location affect the yield of the table power plant.

Power| Ø max. electricity yield / year| Ø max. electricity yield / day
---|---|---
410W (400W) – South; 20°| 455 to 470 kWh| 1.25 to 1.29 kWh
410W (400W) – S; 30°| 475 to 490 kWh| 1.30 to 1.34 kWh
410W (400W) – S; 35°| 485 to 500 kWh| 1.33 to 1.37 kWh
410W (400W) – SEast; 35°| 455 to 465 kWh| 1.25 to 1.27 kWh
410W (400W) – Swest; 35°| 460 to 465 kWh| 1.26 to 1.27 kWh
410W (400W) – E; 20°| 380 to 390 kWh| 1.04 to 1.07 kWh
410W (400W) – W; 20°| 385 to 395 kWh| 1.05 to 1.08 kWh

How to set up the angle?

To adjust the angle, loosen the locking screws on each the telescopic arm and pull out the adjustment pins and turn them so that they do not re-engage. Lift the solar panel further. Allow the adjustment pins to snap into place.
Lift the solar panel until it locks into the first angle of 20°. Tighten the locking screws.
To set another angle, pull out the adjustment pins and turn them so that they do not re-engage (loosen the locking screws).
Lift the solar panel further.
Allow the adjustment pins to snap into place.
The solar panel will automatically lock into the next angle of 30° as you continue to lift it. Tighten the locking screws.
To reach the 35° angle, repeat steps 3 to 5. Tighten the locking screws

First commissioning

After mechanical and electrical installation of the solar table, you can put the system into operation. There should be enough sunshine for this. The solar panel needs to produce at least a start voltage of 22V.

Initial state:

The micro inverter is connected to the solar panel
The micro inverter is connected to the house mains via Wieland plug(recommended) or Schuko/Type13 plug.
The cables are fixed protected from rain and sunlight
The feed line is connected to the mains via a circuit breaker

Proceed as follows:

Plug in the connection cable to the power socket. If not done yet! (Turn on the circuit breaker and any other switches that may be present.)
The micro inverters LED should be flashing red.
After you turn on the AC circuit breaker the LED flashes red until the micro inverter has synced with the house grid.
The micro inverter starts feeding (grid synchronization) within 2 minutes if there is sufficient solar radiation. The status LED indicates the basic function. You can check the feed-in power with a suitable power socket energy meter (needs to be water proof for outside use!).
If you have installed a feed-in meter, you can also use it to check the current feed-in power or energy.

Note: When AC power is applied but the micro inverter is not started, approximately 0.2W of power can be measured for each micro inverter using a power meter. This power is reactive power, not consumption from the utility grid.

LED status

The LED of each micro inverter provides information about the current status. All micro inverters draw their supply voltage from the DC connector/solar panels. Status during power up Until the micro inverter has synced with the grid it flashes red. Then switch-on process usually takes up to 2 minutes. Synced successfully with the grid, micro inverters LED flashes green. Following LED status can occur:

Status after the switch-on process

A fast green flashing LED indicates normal status and an active feed into the grid. If the LED remains flashing red after 3minutes, this indicates an error with solar panel voltage that is too low (below 22V) or a missing AC voltage.
The micro inverter can only start feeding (again) after the cause of the error has been eliminated. The reason for this error could be a faulty solar panel connection / AC connection or the connected grid exceeds / falls below the voltage / frequency range of the micro inverter. If the LED shows no function or remains OFF, the most common cause is that there is no connection to the solar panel or the solar panel voltage is far below the start voltage.

WiFi configuration

The micro inverter of the solar table should be already installed and connected with the house grid. Plugged into a power socket.
The maximum communication distance between micro inverter and router is 20m in open space. Walls, roofs, or other obstacles in between will affect the signal and reduce the communication distance in actual installations.

Troubleshooting

Maintenance work and troubleshooting on the micro inverter may only be carried out by qualified personnel. Modifications to the micro inverter are generally prohibited. The micro inverter is potted, the electronics cannot be repaired. The HMS-400W-1T micro inverter draws its supply voltage from the DC side. To restart the micro inverter, the solar panels must be disconnected from the micro inverter. The start-up process usually takes place within 2 minutes. For troubleshooting purposes, perform the following steps in the order listed:

Check that all AC fuses are turned ON.
Check all connection cables for external damage.
Check all AC side connections for damage or connection errors.
Measure at the connection points. The applied mains voltage must not exceed or fall below the AC voltage range of 180-275V.
Restart the micro inverter by disconnecting and reconnecting the DC power / solar panels. A normal start-up process should be indicated by a green LED (see LED status).
CAUTION!
Never disconnect the DC cables while the micro inverter is generating power.
Measure the voltage of the solar panel to the micro inverter with a suitable multi-meter. The required starting voltage of the micro inverter is above DC22V.
Check the MC4 connectors of the micro inverter and solar panel(s). Damaged DC connections must be replaced.
If necessary, check with your grid operator whether the grid frequency matches the frequency range of the micro inverter.

CAUTION!

Do not attempt to repair the micro inverter. If the above steps do not solve the problem, contact our support or an electrician. The AC connection on the micro inverter cannot be replaced/repaired. If the cable has been damaged, the device should be disposed of. Unless otherwise specified, maintenance work must be carried out with the equipment disconnected from the mains (mains switch open) and the solar panels covered, or insulated. Do not use rags or corrosive products for cleaning that could corrode parts of the equipment or cause electrostatic charges. Avoid temporary repairs. All repairs should be made only with original spare parts. Each micro inverter should be protected by a circuit breaker, but central disconnect protection is not required unless specified by national standards, or by the responsible network operator.

Appendix

Determining the line reserve

The PI Photovoltaic Institute Berlin in cooperation with the German Society for Solar Energy (DGS), the University of Applied Sciences (HTW) Berlin have worked out in a study that it is possible to feed in up to 2.6 amps (approx. 630 W, equivalent to 2 solar modules) with plug-in solar devices in every household with circuit breakers without any safety concerns, without having to make any changes to the house electrics. However, there may be a deviation from the applicable standard for line loading. We have described how to comply with the requirements of the standard and how to test the line in this appendix. If mini solar systems feed into the existing final circuit, the current load on individual cable sections may exceed the designed standard size. To prevent overloading of the cables in the household, they are protected by a line circuit breaker (LSS). This switches off automatically as soon as an overload occurs. As a rule, several sockets and consumers are protected by a common line protection. Due to the additional power of the mini solar system, the currents from the utility grid and the mini solar system can now add up. However, the currents are not detected by the line circuit breaker, so theoretically an overload can occur. You can use the following formula to determine whether the existing line with your circuit breaker is sufficiently dimensioned:
Iz indicates the current carrying capacity of the line, which should be greater than the sum of the rated current of the protective device (circuit breaker in amperes) and the generating equipment (power in amperes). Both Iz and Ig can be found in the following table for the example application below.

Iz = In + Ig
Iz Permissible current carrying capacity of the line
In Rated current of the protective device (circuit breaker)
Ig rated current of the power generation system

The example from the table is based on two loaded copper lines with a nominal cross-section of 1.5mm2, which reflects the line in a typical German household. In the case of a larger cross-section or a different cable type, the permissible current-carrying capacity is different, so that this must be considered separately, in accordance with DIN VDE 0298-4.

Determination of the line reserve

If the cable is a copper cable with a core cross-section of 3×1.5mm2, then the cable is designed for a continuous load of 16.5A (in thermally insulated walls at 25°C). The free capacity is the difference of the line with 16.5A, minus the circuit breaker with 16A. The free capacity is therefore 0.5A in thermally insulated walls. If the solar power exceeds the current of 0.5A, then the circuit breaker should be replaced with a smaller one in order to comply with the requirements of the DIN VDE 2948-4 standard. By exchanging the fuse for a smaller 13A fuse, 13A can now still be drawn from the power grid, resulting in free capacity for the power line with the difference of 3.5A. The power of the solar system could therefore be up to 805W. In the example (right half of the picture), the power of the mini solar system is 2.6A/600W, which complies with the permissible load.

Further safety instructions

Only connect the mini solar system to a permanently connected socket, never to a multiple socket.
If you still have older screw fuses installed, it is mandatory to replace them from 16A to the next smaller fuse.

Disposal

Disposal of the packaging. Sort packaging materials by type upon disposal.
Dispose of cardboard and paperboard in the waste paper. Foils should be submitted for recyclables collection.
Disposing of old equipment (Applies in the European Union and other European countries with separate collection (collection of recyclable materials) Old equipment must not be disposed of with household waste! Every consumer is required by law to dispose of old devices that can no longer be used separately from household waste, e.g. at a collection point in his or her municipality or district. This ensures that the old devices are properly recycled and that negative effects on the environment are avoided. For this reason, electrical devices are marked with the symbol shown here.
