Selection notes for a high-voltage home
Hearth 8 is a compact 8 kWh high-voltage integrated unit. Selection comes down to the voltage window, protocol, power and current limits, usable-energy target, installation environment and the approved inverter list.
One high-voltage unit covers most household energy needs
- Home backupKeep critical circuits (fridge, lighting, comms, medical devices) running through an outage
- Self-consumptionStore rooftop PV surplus and release it at night, raising self-use and lowering bills
- HV hybrid inverter550 V platform, DC-coupled, with PV, battery and grid designed as one system
- Balcony / small PVMicro-PV systems matched with a high-voltage battery pack
- Small commercial backupCritical loads for studios and small shops
