    Solar and battery bank: how to intelligently limit draw from incoming supply?

    We have a 5.5kW incoming supply, which cannot practicably be upgraded due to our remote location in the mountains. Can I use a PV array and battery bank to augment this supply?

    Solar How do I limit or feed inrush current for higher constant current use?
