Before ordering and installation
Confirm the supplied battery capacity in Ah and kWh and the approved PV-array configuration before ordering. The manual lists different PV wattage limits for different configurations; the 165 V Voc limit is not a wattage rating. Ask us to confirm the configuration for your panels.
Use a qualified installer and follow the model-specific manual. Keep the unit in a dry, well-ventilated location. Installation wiring, earthing and protective devices must be selected for the installation.
