I have had an entry-level 1200W pure sine inverter and used it full-time as I'm off-grid. It did just break after 4 years, and at first, that sounded like a short life span, but I have since learned that much like batteries, you're not supposed to use them to full capacity, much like batteries...

Thank you so much for your replies, that is very helpful. I think you're right, I need to toss those 28$ MPPT controllers, I have been wondering why some cost 30$ and others cost 400$. But I'm thinking I need to figure out first why I can't get over 800 Watts, why the go to sleep when I go...

Wow, that is really interesting. But if it is actually a PWM, shouldn't they work together in parallel as my old 30A PWMs did? The part that still puzzles me is that they do 800 watts but nothing above 800 watts.

Thank you.

I have 1240 watt in solar panels. Up til now I had 720 Watts (sitting on the ground) connected in parallel via two 30A PWM controllers to a battery bank of four 100 Ah batteries and two 100 watt panels on the roof through an additional 30A PWM controller connected to the batteries. The 2 roof...
