Winter 2013 I ran into trouble. Two bargain finds combined to create a power overload that tripped the circuit breaker and blew the inverter. The inverter still inverts, I can hear it working, but it won’t output power, instead displaying a “OLP” error.
I went cheap starting out on my solar experiment. So this time I thought, get an inverter that has specifications that matched my environment.
Match your need
For my climate I needed to operate well into the -°C. Like minus 20.
My battery bank when cold regularly needs 15.5 v in absorb charging. And I equalize once a month. Voltages can exceed 16v. So ability to handle a wide voltage range is required.
Voltage spikes, harsh conditions, I needed a tough inverter that was built to handle worst case scenarios.
After some shopping around I realized I would be spending twice the money I had originally planned for.
Your first quandry with any solar system is where the heck to put it.
You have to hang panels that are 3 feet by 5 feet in my case and weight 50 lbs each. You have to store batteries: 720 lbs of lead for me. And you need a safe dry spot for your charge controller, your inverter, your combiner boxes. And, if you’re like me, cheap, you have to do it on a limited budget.
