I have a cheapo 600W GTE connected to (2) 240W panels connected in parallel. It has been operating fine for about 3 yrs but now I am finding that it goes in an out of synchronism on a regular basis.
The GTE has a row of LEDs that flash from end to end back and forth. When out of synch it stops moving in the sequence, but tries and just flickers. When out of synch the I measure 36VDC (unloaded) when synched it drops to 30VDC. I also have an AC ammeter and VM on the output. When out of synch I read 122VAC & 0 amps. Synched I read 120VAC & 2 to 3 A AC.
My experience show that when a SS component fails it usually stays that way. But in this case it comes back to life. It is not the ilanding protection causing it because the utility voltage is solid.
Any ideas? I know...I know....buy a good inverter !!!
