Hey everyone! I've been diving into the idea of setting up a whole home battery system after seeing my latest electricity bill. I currently have a 13.60 kWh solar setup with 34 Aptos panels that convert to AC at the panel, connected to an Enphase IQ combiner 4 that ties into the grid. On average, I send about 20 kWh back to the grid daily but use around 12 kWh from the grid each night. Is it reasonable to think I can capture some of that surplus? From my research, sizing multiple off-grid inverters with a 15 kWh battery pack seems to be a good route. I'd love to hear your thoughts on this! Any recommendations for products would be appreciated!

It really depends on your nighttime electricity costs. Since you're generating more than you're using, it's definitely possible to capture that surplus. However, think about the return on investment (ROI) for the setup. Also, you might need a different inverter, depending on the system you choose!
Are you aiming to go completely off the grid with this system?
I can relate! I’m in a similar situation. During the summer, it can get super hot even after sunset. I have net metering until the 2040s, but when that changes, I plan to install a 'helper' ductless mini-split AC that will run on an inverter linked to its own battery. My solar setup recharges it during the day, which helps keep things cool at night.
