Target Group
Growatt SPA TL3 BH inverter must be installed by professional electrical personnel who have obtained the certification of the relevant departments. We have two kinds of energy storage machine for different battery one is for lithium battery and the other is for lead-acid battery, we suggest: customer should decide which kind of energy storage machine you want, Growatt can provide only lithium battery with energy storage machine, customer can choose lead-acid energy storage machine with no battery provide by Growatt while they can buy these battery from market easily. Especially if customer choose energy storage system with lithium battery(which must be provide by Growatt) but used for lead-acid battery or used lead-acid battery for lithium battery model, it will be dangerous. Installer can install energy storage machine of Growatt SPA TL3 BH Series rapidly and troubleshooting, build communication system through read this manual carefully.If you have any questions in the process of installation, you can login in www.growatt.com and leave some message.Or you can call our 24-hour service hotline+86 0755 27471942.

Product Description

Growatt SPA4000-10000TL3 BH only use meter as its sensor, before installing your system you should know something as below:

1. The cable of meter is suggested not longer than 15m. Because of this, you should consider the cable length between SPA and combiner box.
2. The meter must installed in the L line.
3. The installation layout of energy storage system at home shows as following:

Installation of SPA

1. First estimate the size of the inverter on the wall;
2. Determine the location of the drill hole through the cardboard (installation guide), put the cardboard on the wall and make sure the top edge of the cardboard is horizontal.
3. Mark four points at the wall via the hole of the paper board, then remove the cardboard.
4. Drill four 8 holes at the mark point, the depth is not less than 55mm.
5. Knock four explosion bolt into 8 holes (As the chart 5.8b below).
6. Hang the energy storage machine on the four setscrews (As the chart 5.8c below).
7. Lock the nut of setscrew (As the chart 5.8d below).
8. The whole installation has finished.

AC Output terminal and EPs output terminal connection steps as follow:

1. Step 1 :Uninstall the AC terminal as below chart.
2. Step 2 : Thread cables through pressure screw, seal ring, threaded sleeve in sequence, insert cables into connection terminal according to polarities indicates on it and tighten the screws.
3. Step 3 : Push threaded sleeve on to connection terminal until both are locked tightly.
4. Step 4 : Plug the socket into AC output terminal, clockwise rotation to tighten the socket, counterclockwise rotation to loosen the socket.

The following diagram shows the AC output terminal of the Australian machine connection steps, EPS output terminal connection steps consistent with the above steps.

AC output terminal and EPS output terminal connection steps as follow:

1. Step 1 : Uninstall the AC terminal as below chart.
2. Step 2 : Thread cables through pressure screw, seal ring, threaded sleeve in sequence,insert cables into connection terminal according to polarities indicates on it and tighten the screwS.
3. Step 3 : Push threaded sleeve on to connection terminal until both are locked tightly.
4. Step 4 :Plug the socket into AC output terminal until it is locked. Use a flat-blade screwdriver to hold the buckle and pull out the AC terminal.
5. Step 5 : Plug the AC terminal into the inverter AC port.

The recommended wiring diagram is as follows:

Note:
This diagram is an example for gird system without special requirement on electrical wiring connection.

Note:
This diagram is an example for Australian and New Zealand gird system where neutral line can’t be switched.

Note:
This diagram is an example for customer who only wants to use the on grid storage system.

Notice:

• If you want to use on gird only, please refer to chart 5.21 Connect with AC grid and float EPS OUTPUT.
• If you want to use both on gird power and backup power, please refer to chart 5.19 and 5.20.Connect with AC grid and EPS OUTPUT like the chart show.
• On grid terminal and off grid terminal can’t directly connect together.
• Off Grid terminal can’t connect to grid.
• If you want to use on gird and off grid, you can use ATS (automatic transfer switch) like chart 5.19 and 5.20 before or ask Growatt for help to connect them.
• The first start of system needs Grid power.

EPS output does not support half-wave load type devices, such as hair dryers.

Connection of battery terminal
Similar to the traditional inverter connecting, the input of battery can be realized by using MC4 terminal, the detail steps are as follows:

1. Step 1 : Turn off battery switch.
2. Step 2 : Insert battery panel positive and negative cables into MC4 terminal, then connect positive pole(+) of connection cable to positive pole(+) of battery input connector, connect negative pole(-) of connection cable to negative pole(-)of battery input connector. Please pay attention to battery input voltage and current within permission Limit:
3. Max battery voltage: 550V
4. Max battery input current : 25A
5. Max battery input power : 1 0000W

Remark:
We suggest you use the cable?:4mm2/1 0 AWG to connect

Note:
We suggest the distance between battery and SPA no longer than Sm, and The power line area must be larger than 1 0AWG.

Connection of meter terminal
When customer needs to use meter to monitor the energy flow, the meter terminal connection steps are as follows:

1. Step1 : Reference 5.2, make LAN cables with RJ45 terminal.
2. Step2 : Thread the swivel nut over the LAN cable.
3. Step3 : Press the cable support sleeve out of the cable gland.
4. Step4 : Remove the filler plug from the cable support sleeve.
5. Steps5 : Route the LAN cable through an opening in the cable support sleeve.
6. Step6 : Thread the LAN cable through the cable gland.
7. Step7 : Insert the RJ45 plug of the network cable into the “METER-1” pin connector on the inverter until it snaps into place.
8. Step8 : If no other cables need to be installed, lock the waterproof cover to the inverter with screws.
9. Step9 : Screw the swivel nut onto the waterproof cover.

Note:

1. Meter must be provided by Growatt. If not, maybe meter can’t communicate with SPA inverter.
2. The more detail describe of meter installation, please turn to meter user manual.

Remark:
Meter wire (15m in length) specification: RJ45, standard LAN line (one end with 8P modular plug, the other connected with transformer). But if the length is not enough, customer can add cable, so the length can be increased to 25m max, the operation is as follow chart:
