Long story short... we bought acreage with nothing on it with the intention of building a house and living off grid...eventually... but circumstances forced us to move to the acreage waaaay before we were ready, and we needed to put things into place quickly and with minimal funds. So here's the problem: we put together a pv system just to get us started with a little bit of electricity, but with plans to expand. We don't need a tonne of power, but it seems like we should have a little more power available than we do. Here's what we have:
4 x 250 w solar panels wired as 2 separate series, each pair connected to its own 60A mppt charge controller. Then we have 4 x 6v 230ah deep cycle agm batteries connected as a 2x 2 series/parallel to create a 12v system with 460ah, and finally we have a 2000w modified sine wave inverter.
We live in a place with very hot sunny summers, so there's no shortage of sun right now...direct sun is on the panels from 8am-5pm We are trying to run our starlink satellite (100w), and a small chest freezer (150w), plus occasionally charging a laptop, and 3 phones. We only charge the phones and laptop during the day when the sun is shining, and we can only run the freezer until the sun is off the panels bc otherwise the batteries are depleted and the inverter gives us an alarm at 9.8 v by late evening. Even with the freezer being shut off (and the sattelite receiver being the only thing plugged in) usually we have to shut the inverter off by midnight so we have a little power left first thing in the morning before the sun gets going again. This isn't optimum, obviously, but it's all we could swing in the time we had. Suggestions? Ideas? Obviously we have done something wrong... but what?
