Frequently asked questions
Does it need a three-phase supply?
Yes. The 3:3 configuration means three-phase input and three-phase output at 400V, so it must be connected to a three-phase supply.
Can the battery capacity be increased?
The listing states it is expandable to 3 modular battery strings. Check the Schneider datasheet for compatible battery modules and the runtime at your load.
