The old inverter I bought second hand for $20 bit the dust. In part due to my lack of cable strain relief which created contact between ground and negative, oops :\ lessons learned. I bought this new guy which works so much better I think the old one was on the way out anyway. I especially love the fact it comes with a remote start/stop. Since we rarely use 110AC and the solar shed is 50′ from the house, it’s perfect to remove phantom loads. It’s not like we remember to ever turn it off, but we can 🙂
We just upgraded our batteries from 3 * 35Ah lead acid (right) to 3 * 155Ah deep cycle AGM (left). The difference is like night and day; pun very much intended. These bears weight 90 lb each. We added lights in the house and are able to make it through several overcast days without loosing power. I still need to wire in another charge controller and clean up the mess of wires in the solar shed. The old system will get re-purposed for raspberry pi instrumentation around the homestead.
