The good news is that it's entirely possible to add battery storage to an existing solar panel setup. So-called “storage ready” systems are already equipped with an inverter that can easily direct excess power into a battery.

You would need around 24v 150Ah Lithium or 24v 300Ah Lead-acid Battery to run a 3000-watt inverter for 1 hour at its full capacity Here's a battery size chart for any size inverter with 1 hour of load runtime Note! The input voltage of the inverter should match the battery voltage.

The real cause is often a limit in the path from battery to inverter. It can be a strict low-voltage cutoff, a surge that exceeds the BMS limit, or a simple voltage drop in the cables. The inverter can click off when a compressor or pump.
