6500 EX battery bank size

[TJOPT]

I would guess that the question I have is already answered somewhere in the forums but for the life of me, I cannot find it. I have two 6500 EX and plan to install a 15-16 kW solar array. My question is the maximum battery bank size that two 6500 EX inverters will charge. My hope is that it would charge 40 kWh worth of batteries in a 48v system

It will depend on how much energy you pull out of them overnight and how much energy you use during the day. If it is any help, I have 6.8k of panels, two '6500s, 60kWh of batteries. I pull about 15kWh over night and my batteries are fully recharged no later than 2M. That includes an additional 5kWh of daytime usage.

That's two in the afternoon-no idea where the emoji came from!

Thank you very much for the information

As long as you have the array to fill em, as far as I know, the inverters don’t care how big the battery bank is

Mine is 62kWh, four 304aH batteries with 15.2kWp. Works great on my shop so far. Those noisy fans increase my idle consumption to 1.9A each vs my 1.3A per SolArk12K.

I have 105kWh bank on mine.

EDITED: I've made this my build thread, so while there is an OP question below if you keep reading I'm slowly posting updates of my entire system. Mods please feel free to move if desired. System summary: (2) EG4 6500s for 120/240V config. (40) Hyundai 390W panels in 10s4p to stay under 500VDC...

I went 1 year with 30 kWh....recently added another 30 kWh for a total of 60 kWh.

What size is your solar array?
