RCT Power Battery 7.6 is a high-voltage storage unit with LiFePO4 cells, to be installed on the floor in an indoor room. It has a nominal capacity of 7.68 kWh, of which 6.91 kWh are usable at a 90% depth of discharge.

It can be extended to the double tower (DT) configuration, which reaches 15.36 kWh nominal. The connection is made over a CAN interface to an inverter from the RCT Power Storage DC family.

The warranty runs ten years from first installation; the manufacturer treats the accumulator as defective if its capacity falls below 80% of nominal.

03 · Summary

Pros and cons

In favour

A double tower (DT) configuration exists: two towers reach 15.36 kWh nominal.
It uses LiFePO4 cells.
The warranty lasts ten years: the accumulator is defective if capacity falls below 80% of nominal.

Worth knowing

It is installed on the floor in an indoor room: it needs a covered space and is not meant for outdoor use.
The operating range is +5 to +40 °C: in a room that drops below +5 °C the battery falls outside that range.
The declared pairing is with RCT Power Storage DC inverters: with an inverter of another brand, compatibility must be checked before buying.
