Anyone in Ft Lauderdale that can help me with my batteries?

I have installed a new 2000 watt pure sine wave and have 6 120 amp hour get batteries. Every time I put a heavy load on it it shuts down because of low voltage input? Anyone in the area qualified want to come help me?

Yeah, I'd check your cables. My 2000 watt requires 2/0 cables. That cable is about 1/2" dia. without the insulation. It could be starving for amps.

It's also very accessible.
As a Maintenance/Repair Machinist for over 40 years I keep everything spic-N-span. The first sign of trouble on motors, compressors and other reciprocating/spinning machinery usually shows up on the outside by leaks or parts coming loose. So keeping it clean is a part of doing scheduled maintenance. And as another member states "Rust never sleeps".

Sorry!

Re: Anyone in Ft Lauderdale that can help me with my batteries?

What is Ur distance from inverter to batteries ?
The further away Ur inverter is from batteries the higher the resistance will be and U will need bigger wire size.....M U C H BIGGER
To avoid the problem install the inverter as close as posible to the battery bank.

For testing try to do the same load test with shorter temporay wires ...max.1 meter/3 feet length
Donīt look any further until U have performed that test

Great

Just to make shure everything is OK
Next time You got all them heavy loads switch on
Touch the wires with Your hand
You should not feel any heat

Should we ever meet in heaven or hell
you can invite me for a drink

Re: Anyone in Ft Lauderdale that can help me with my batteries?

I would suggest a fuse in the positive cable near the battery post - 250 amp would be a good choice.
