To turn on the battery simply switch the power to the on position and hold the SW button for about 3 seconds until you see the lights start to flash.

We do not have the main cables or RJ45 cable however when you open the lid you will see the main + and - ring terminals as you can see in the photos. You can make your connections right to those busbars.

You can use these batteries without communication if you want. The BMS works like normal and also has balancing.

Communication will work however we cannot help with technical advice. Here's what we know about the communication settings.

R485 Baud Rate: 9600 or 115200
CAN Baud Rate: 500K
RS232 Baud Rate: 1200

The first dip switch ON baud rate is 9600 and OFF is 115200
Dip Switch 2, 3, 4 in order for the following
Master battery - off (2), off (3), off (4)
1st battery group - on (2), off (3), off (3)
2nd battery group - off (2), on (3), off (4)

These came in the original packaging but the branding has been removed as you can see in the photos and we will ship them out of the boxes and on pallets. They are being sold as is and unbranded. We guarantee they arrive balanced and working but we cannot help with programming your inverter or with communication protocols. This price is insanely low for unused rack mount batteries like this. Again, we opened each one to check everything out and confirm the batteries are perfectly balanced and also made sure they turn on and off normally.

These have to ship on a pallet. The more you buy the cheaper shipping is per battery. Or you can pick up from our Bensalem, PA location or free. Our shipping rates include residential and lift gate service if needed.
