About a month ago I installed a 12000xp with 2 indoor 14.6 wall batteries. The system is grid tied and the 12000xp powers a separate sub panel that powers most of the house. At peak load the largest demand on the system is under 5000 watts. The majority of the time the output is only about 2200 watts. Everything has been working fine except when I went to use a small throw heater blanket. The outlets that are fed from the 12000xp won’t turn on the blankets. I can plug the blankets into an outlet powered by the grid and they work perfectly. I get the same results with every outlet and circuit coming off the 12000xp. Everything else works fine when plugged in just not the blankets.Why?
