I'll post the error messages from my 2006 Sunny Boy 2kw inverter. Is it time to get a new inverter? What inverter should I buy?
The model number is WR21UW9E?
SMA says: "The message Fac-Bfr means that the power frequency is not within the permissible range."
It's getting 294V in from the photovoltaics and producing 0 watts.
It's produced 15,559 kWh over 56,571 hours. At $0.10 per kWh that's $1,500 of electricity? From a system that cost $25,000 in 2009? With subsidies I paid $5,000.
