POWERSET21

This highly efficient hybrid inverter is suitable for private and commercial photovoltaic systems with an output of up to 6.5 kWp and a low-voltage battery storage system.

The overvoltage protection for the solar panels and the mains disconnector are integrated in this unit.

The power feed into the grid can be set variably between 0% and 100%. Operation without mains feed is possible.

The power data can be conveniently read on the unit or on the app.

In combination with the KKTNVB5.1 battery storage included in this set, the energy generated during the day is stored and can then be consumed at night.

The 1-Phase Ecco emergency power function: In the event of a power failure, the hybrid inverter switches off the grid and switches to island mode. Within approx. 6 seconds after the power interruption, one phase in the domestic grid is supplied with power again. All relevant emergency power consumers, such as heating and light, should be connected to this phase. In island operation, only one phase is supplied with power until the batteries are empty.

Useful additional device: The separately available SDM630MCT 3-phase current measuring device. Since the HKW5000P1 can only feed in and measure current on one phase without an extension, the energy that exceeds the consumption of phase 1 is first charged into the battery and then fed into the public grid. With the SDM630MCT extension, the HKW5000P1 feeds exactly as much power into the grid via one phase as phases 1, 2 and 3 consume, even if the battery is not yet fully charged. In this way, in the optimum case, only a power consumption of 0W is measured at the main power meter, as the power consumption of all phases is offset (netted) against each other at the main power meter. Please note that the emergency power function with this extension is still only possible on one Phase.

Comfort Emergency power on 1 phase is only available when the system is connected to the house fuse box. One phase from the mains goes to the house power station and from the house power station to the fuse box.

The hybrid inverter is black-start capable. If the batteries are empty, the inverter switches off and restarts without mains power as soon as the PV modules have recharged the batteries. As a rule, the system generates enough power even in winter to keep the heating and lights working all the time.

KKTNVB5.1 Battery storage

The system can be upgraded to up to 4 battery storage units. In the best case, all batteries are commissioned at the same time, otherwise the ageing effects will have a negative impact on the performance of the newer batteries. Please take this into account when calculating your electricity consumption.
