I was looking for a 5000 watt inverter and a friend told me he has two 2500 watt inverters he would give me that could just be wired in parallel for the same result. Anybody here done that???
I estimate my daily average power usage at just a hair over 4kw
I have a 24kWH lithium battery bank. I run a 2kW inverter at 24V. I have a spare identical inverter and was wondering if I can put them in series and rewire my battery bank to 48V? I know phasing (and blue smoke!) is a problem/issue when you parallel two inverters but I was wondering if putting them in series would be OK. So would still then get 4kW from 48V??
2.1 Kw Suntech 175 mono, Classic 200, Trace SW 4024 ( 15 years old but brand new out of sealed factory box Jan. 2015), Bogart Tri-metric, 460 Ah. 24 volt LiFePo4 battery bank. Plenty of Baja Sea of Cortez sunshine.
How old is this thread?
Please can I connect my 2 inverters(3kva &5kva) with 18batteries (200ah 12v) in parallel inverter setup .
Is your battery bank 200 ah @ 12 volts, or 3,600ah @ 12 volts? (18x 12 ah batteries, or 18x 200 ah batteries?)
In reality, I would humbly suggest that the practical maximum 12 volt battery bus could support is around 1,800 to 2,000 watts on a ~800 ah @ 12 volt bank (lithium or AGM can do a bit larger inverter).
Generally speaking, inverters need to be designed for parallel operation. Not all are, and I'd be very surprised if a 5kva inverter 12v was. As Bill notes, 5kva is really too big for a 12v bank. If lead-acid, 18 in parallel could be an issue as well.
