About the product
Panels only generate while the sun is shining; storage delivers that energy when you need it. The daytime surplus waits in the battery and covers evening and nighttime consumption. When the grid goes down, the hybrid inverter switches to battery power, and the loads connected to the battery keep running.
We install modular low- and high-voltage batteries in homes and high-voltage cabinet systems for businesses. Capacity is determined during the site survey based on your consumption profile and the loads that must keep running during an outage; the modular design allows for expansion later.
Highlights
- LiFePO4 (LFP) chemistry

How does it work in your system?
- 01
Charges during the day
When panel output exceeds consumption, the difference charges the battery.
- 02
Used in the evening
After sunset, your home runs on the battery; grid draw goes down.
- 03
Kicks in during outages
When the grid goes down, the inverter switches to the battery and the lights stay on.
- 04
Protected by the BMS
It monitors the voltage and temperature of every cell and prevents overcharging and overheating.

Frequently asked questions
Is LFP safe?
LFP chemistry is far more resistant to thermal runaway than NMC; in tests, smoke rather than flame is usually seen. Proper installation and a BMS are still required.
Can capacity be expanded later?
With modular batteries, yes: you add modules from the same series.
How long will it last during an outage?
It depends on the appliances that need to run and the capacity; we calculate it together during the site survey.
Energy flow
Your energy stays with you, even after sunset.
- Kicks in during outagesWhen the grid goes down, the system switches to the battery. Lighting, the fridge, air conditioning or a production line connected to the battery keeps running.
- Daytime energy, yours at nightSurplus energy the panels generate during the day waits in the battery for use in the evening and overnight.
- ScalableModular batteries for homes, high-voltage cabinets for businesses. Capacity grows with your needs.
