- Modifications to the surroundings of the device must comply with the applicable national and local standards
- When working on the PV generator, in addition to disconnecting this from the grid it is also necessary to switch off the DC voltage using the DC isolator switch on the device
Proper use
The device is a transformerless PV inverter which converts the direct current
of the PV generator into grid-compatible three-phase alternating current and
then feeds the three-phase alternating current into the public power grid.
The device is built using state-of-the-art technology and in accordance with
the recognized safety rules. Nevertheless, improper use may cause lethal
hazards for the operator or third parties, or may result in damage to the
product and other property.
The device is intended for indoor and outdoor applications and may only be
used in countries for which it has been approved or for which it has been
released by KACO new energy and the grid operator.
Operate the device only with a permanent connection to the public power grid.
The country and grid type selection must be commensurate with the respective
location and grid type.
The requirements of the grid operator must be met for grid connection to take
place. The permission of the relevant authorities may also be required in
order to secure authorisation to connection to the grid.
| Country | Standard |
|---|---|
| EU | Harmonised document – HD 60364-7-712 (European implementation of the IEC |
standard)
The device must only be operated with PV arrays (PV modules and cabling) of
protection class II, in accordance with IEC 61730, application class A.
The name plate must be permanently attached to the product.
Any other or additional use is not considered proper or intended use and can
lead to an annulment of the product guarantee. This includes:
- Use of a distribution system that is not described (grid type)
- Use of sources other than PV-strings
- Mobile use
- Use in rooms where there is a risk of explosion
- Use in direct sunlight, rain or a storm or other harsh environmental conditions
- Outdoor use in environmental conditions that exceed the limits stated in the technical specifications >Environmental data
- Operation outside the specification intended by the manufacturer
- Overvoltage on the DC connection of over 1100 V
- Modifying the device
- Standalone mode
Protection features
The following monitoring and protection functions are built-in:
- RCMU (Residual Current Monitoring Unit)
- Overvoltage conductor / varistor to protect the power semiconductors from high-energy transients on the grid and generator sides
- Device temperature monitoring system
- EMC filter to protect the inverter from high-frequency grid interference
- Grid-side varistors grounded to earth to protect the product against burst and surge pulses
- Anti-islanding detection according to the current standards.
- Isolation detection / residual current monitoring and disconnection function to detect isolation faults.
NOTE
If the device is connected, the overvoltage conductors / varistors contained
in the device have an impact on the electrical system insulation resistance
test as per HD 60364-6 / IEC 60364-6 Low-voltage installations- Part 6:
Verification.
IEC 60364-6 6.4.3.3 describes two options for this case. The first option is
to disconnect devices with an overvoltage conductor or, if this is not
practicable, then the test voltage can be reduced to 250V
Description of the device
Mode of operation
The device converts the DC voltage generated by the PV-modules into AC voltage
and feeds this into the power grid. The starting procedure begins when there
is sufficient sunlight and a specific minimum voltage is present in the
device. The feed-in process begins once the PV generator has passed the
insulation test and the grid parameters are within the requirements imposed by
the grid operator for a specific monitoring time. If, as it gets dark, the
voltage drops below the minimum voltage value, feed-in mode ends and the
device switches off.

2 The “Max. input current” is the maximal theoretical value during operation
at full power and minimal MPP voltage. The inverter will clip to the maximum
AC power output.
The “Max. short-circuit current (ISCmax.)” defines together with open circuit
voltage (UOCmax) the characteristic of the connected PV generator. This is the
relevant value for string sizing and is the absolute maximal limit for
inverter protection. The connected PV-Generator must be designed, that the max
short circuit current is below or equal to ISCmax of the inverter under all
foreseeable conditions. In no condition the design may result in a greater
short circuit current than ISCmax of the inverter.

Checking the PV generator for a ground fault
| DANGER
---|---
DANGER| Risk of fatal injury due to electric shock!
Severe injury or death will result if the live connections are touched. When there is sunlight present on the PV generator, there is DC voltage on the open ends of the DC cables.
› Only touch the PV generator cables on the insulation. Do not touch the exposed ends of the cables.
› Avoid short circuits.
› Do not connect any strings with a ground fault to the device.
NOTE
The threshold value above which insulation monitoring reports an error can be set on the mobile device under Other protection settings – Minimum insulation resistance.
Ensure that there is no ground fault
1 Measure the DC voltage between the protective earth (PE) and the positive cable of the PV generator.
2 Measure the DC voltage between the protective earth (PE) and the negative cable of the PV generator.
ð If stable voltages can be measured, there is a ground fault in the DC generator or its wiring. The ratio between the measured voltages gives an indication as to the location of this fault.
3 Rectify any faults before taking further measurements.
4 Measure the electrical resistance between the protective earth (PE) and the
positive cable of the PV generator.
5 Measure the electrical resistance between the protective earth (PE) and the
negative cable of the PV generator.
ð In addition, ensure that the PV generator has a total insulation resistance
of more than 2.0 MOhm, since the device will not feed in if the insulation
resistance is too low.
6 Rectify any faults before connecting the DC generator.
Recommended standard connection
Possible wiring
Two DC strings for each MPP tracker
The MPP voltages of the two DC strings can be different. They are supplied
____by separate, independently operating MPP trackers (MPP trackers A and B)
Number of modules per string:
____P max : per string < 0.6 * max. recommended PV generator power
____MPP tracker A+B together < max. recommended PV generator power
____Imax: Depending on PV generator
__The input current per MPP tracker must not be exceed 40 A
Connection in parallel operation
Possible wiring
Both MPPTs must be connected individually to the generator junction box.
The DC inputs can also be connected in parallel. In this case, only lines with
____the same MPP voltage may be connected in parallel(U n1 =U n2 =U nx )
Number of modules per string:
When using the MPP Trackers in parallel mode, the maximum allowed power is 1,1x rated power. Also the maximum MPPT current is limited by the lowest value of all MPPTs.
For example, if the 15kW inverter is used in parallel mode, the maximum allowed power is 1,1x 15kW = 16,5kW and each MPPT current is limited to
__20A (since one MPPT is rated for 32A and the other is rated for 20A).
