So far so good
I'm fairly sure the complaints of fried solar inverters are from wrong connections and not understanding the configuration instructions in the manual. Never connect the neutrals together, this is so easily done when working on a fuseboard with dozens of same-colour neutral wires all over the place ! My 5000kva solar inverter is working fine. I had turned on the inverter power save mode which caused the unit to cycle on and off when connected to a small load. I would have been convinced the unit was defective if I hadn't studied the manual to learn what each function does.If the unit fails then I'll be sure to provide an update. The inverter is deliberately oversized. I only have 2.2 kw of solar panels connected with the option to add another 1.5 kw in the future. This is plenty for my needs running an office, fridge, computer, small appliances, most lighting and occasionally a 2kw oven. One small caveat is that the inverter uses 1.2 Kwh per day which is 27% of the average collected solar power on a winter's day. Or about 6% of the average collected solar power on a summer's day.
