Hi,
I have decided to go with six of the LVX 6048 WP inverters running in parallel to handle the loads of my project. I am running 10 bitcoin miners that can range from 1000 to 3200 watts each based on my adjusting. I also have four 300 watt exhaust fans.
The loads are USA single phase (120V/240V) and could reach as high as 34,000 watts if I really pushed things.
I have attached an image diagram to help with my questions:
3) In the LVX 6048 WP manual it recommends a 200A breaker for the batteries. Each inverter has a maximum battery discharging current of 150A, and 120A charging.
I have three 48V 280Ah LifePO4 battery banks, each will have its own breaker on the positive side to serve as protection and a disconnect when working on the system. In a hypothetical situation where there was no solar, and the inverters were running at 34,000 watt output, do you recommend using a larger breaker for each battery than 200A? I worry about 200A being too low, tripping one of the breakers unnecessarily. Perhaps something like 250A or 300A if the system was to pull closer to 1C.
1) I'd like to protect each inverter with a Class T fuse. Ian from Watts247 had a video where he said that 200A breakers for the batteries are overkill and recommends a 125A. I may be being overly cautious, my math is:
6 inverters @ 6000w each
6000 / 48v = 125A / 0.8 = 156.25A ~ 175A Class T fuse.
2 & 4) Also in the manual it recommends 2 gauge wire for the battery connection. Is this sufficient or should be using 1/0 on the battery side?
I am using 1000A busbars to connect everything together.
Thank you, and I appreciate any advice!
