1,290W solar setup on our backyard office. How would you size the battery bank for full off-grid?
Hey guys, we’ve got a 1,290W solar PV array installed on our backyard WorkPod, currently powering a standard office setup: laptop, dual monitors, standing desk, LED lights, and a mini-split AC.
While it easily handles daytime loads on-grid, we’re optimizing the battery configurations for 100% off-grid energy independence. Based on your real-world setups, what battery capacity (kWh) and inverter combo do you find most reliable for handling mini-split surge currents while keeping reserves for overcast days?
Would love to hear how the community approaches micro off-grid sizing for structures like this!
