Got power at ~11PM.... hurray. MPSTEVE for these 3 days I had a 5500 W ~8600W peak. It kept my pellet stove, well pump, lights in master bedroom, kitchen and living room, 2 refrigerators with freezer, plus from the kitchen I took an extension where I plugged my reef tank plus fuge and another Discus tank. And to the house lines there where plugged 2 Angel fish tanks (65G , 40G, 75G, 45G and 30G) and a 35 G brute with my new Marine water for my weekly WC all heated to 78 and the discus I reduced it from 85 to 81.
When all the lights where ON and all tanks fully working the system was in the limit. 4-5 times during the day, if someone used the toilet and the well pump started, tripped the generator, but sometime it didn't. Meaning it was really in the limit of their capacity. BUT did the job. No complains at all.
I am writing all this info to give an idea if someone wants to buy a generator.
Nevertheless, I think I will invest in one as mentioned 8000W 10000 W peak dual fuel to have that extra power and avoid,any tripping. And the dual fuel to use propane (BQ Tanks) and gas. That will give a little more of flexibility. They are ~$800 -$1000. Not cheap, but neither too expensive for this hobby.
