Photovoltaic system is mainly divided into five modes: “self-use, surplus power to the Internet”, “self-use, surplus power not to the Internet”, “full grid-connected”, “off-grid” and “parallel / off-grid”.
Let's walk through a complete example: Daily power usage: 2,000 Wh. With LiFePO₄ at 80% DoD: 200 Ah ÷ 0. You'd need at least a 12 V, 250 Ah battery bank.
