I'm having recurring issues with a low battery cutoff on my solar inverter and charge controller. My system operates a 1/2 HP rocking piston pump (120v, 3.5 amps) for about 2 hours each day in direct sunlight, which then pumps water to a pond diffuser. The only other devices connected to the inverter are two USB fans that activate with a programmable timer when the pump runs. I've set it up with a 30 amp charge controller, a pair of 12v 100 ah batteries in parallel tied to a 1,000 watt inverter, and two 200 watt panels that came from a friend, though I'm not sure how well they've held up. Since this is my first solar project, I'm concerned that either my system is underpowered or there's an issue with the panels. Any advice would be appreciated!

Are you running your inverter continuously or just when the pump is on? That could really affect battery usage and how your system performs. If it's direct to the batteries, try to check the battery health and maybe consider running the inverter only when needed. It might help with the low battery cutoff issue you’re facing.
I second that! Running the inverter continuously can drain your batteries fast, especially if it’s a low-efficiency setup. Keep an eye on your battery levels and maybe get some monitoring in place.
