Best Praise
+4 pts“I run my whole house on two anker f3800 with a double power hub. I run a 13000w predator generator 3-4 hours a day, a 6000w would be enough if that is all its used for. I plan to add solar in the spring. https://www.ankersolix.com/products/f3800”

+1 pts“>A dual Anker SOLIX F3800 with expansion batteries costs around $10,000 and provides about 15 kWh of power. 😮 Damn! Glad I went DIY. 48V 100ah batteries are as low as $700 each right now. I could make a bank that is 68.5kWh for the same investment. Maybe at some point, but with a good amount of panels or using a generator to top them off as needed like you mentioned, I think the 8-ish I have now will suffice.”

+10 pts“LiPo (lithium polymer) batteries are old style Li-Ion cells and are dangerous batteries. The River 2 series uses LiFePO4 (also known as LFP) not only have a longer life, they don’t burst into flames when something goes wrong.”

+3 pts“Startup/Shutdown Amps on my Vevor DH, not quite 1 year old yet, requires around 12A. Make absolutely sure any power station you buy can output more than DC 10A because A LOT of them don't. My Ecoflow River2 Max does not output more than 10A so I can't use DC off of it to run my DH. I reverted to using a 30Ah LiFePO4 and it will run my DH just fine for about 7-8 hours at an outside ambient temp of 25f to a low of 17f, is what I experienced and the battery was around 20%. That was with settings where inside my tent was around 51f - 55f. I do have both solar and DC-DC charger but will be looking to upgrade to a LiFePO4 battery in the 200Ah range.”
