Help!!!
So my system was working fine yesterday morning. Left a campground and headed to the next one system was inverting as normal. Arrived next place and hooked up grid power, everything seemed fine. Went to the store came back to no power anywhere. Cebo said batteries were at 100% invertors said low battery, charge controllers said 18v. Switched everything off, waited, power back on and after trying everything I could think of and or find on internet I have the following:
System will work while inverting, batteries will charge from solar. Power from grid is present, tested voltage from poll to rv, everything seems correct. Both multipluses each have 120v incoming but will not switch to grid power. If I power up the generator multipluses will recognize as grid power and switch to grid power. When just grid connected cebo screen says "active AC input" - disconnected. while generator is on it says - AC IN1 and everything seems ok. shut off the generator and it immediately goes back to inverting. Ugh!!
Please any help would be a blessing, currently at a campground with family on vacation. Full timers
