4 reviews for SOK Battery | 100Ah 48v | User-Serviceable Rack Mount Battery

  1. Dave F (verified owner) –

    I picked up 2 of the 48V server rack batteries. Packaging and Shipping were perfect. Everything in my new system is working perfectly. Great customer support from the team. I had a communication issue between the battery and my inverter. CC worked patiently with me and got the issue resolved going above and beyond my expectations.

    Much appreciated!

  2. Jay Heil (verified owner) –

    Just bought 8 of these and I cannot begin to tell you how happy I am with them and the people at CC. Absolutely zero install issues. So clean, easy and simple.
    I wrote a detailed review on the Outback forum for those that want the details: https://forum.outbackpower.com/viewtopic.php?t=17400.

    Only had them up for 4 days but been perfect so far. Everything is cool to the touch even when I was charging and discharging at up to 9.5kw. I’m probably going to end up getting 5 more as 25kwh doesn’t last as long as I thought it does 😀

  4. Jeff A (verified owner) –

    Fantastic company, great products, awesome customer service! I’ve been working with Current Connected for awhile now. and have always found them to be helpful, courteous, professional and highly knowledgeable. Thank you for solving our battery dilemma with 6 SOK server rack batteries…and just as importantly, patiently answer all my questions!

Question:

Is this compatible with Sol-Ark Inverters?
Dexter

Answer:

Yes! An added bonus is that this battery supports full closed-loop communication with ALL Sol-Ark Inverters. In fact this is the easiest inverter on the market to setup battery communications with. You can read more about this battery communicating with the inverter over in the instruction manual page dedicated to Sol-Ark Inverters here: https://www.currentconnected.com/sk48v100/manual-4-4/

Question:

Can I pickup from your warehouse?

Answer:

Please refer to our FAQ here: https://www.currentconnected.com/faq/

Question:

If my inverter doesn't communicate, can I still use this battery?
Dexter
17-Dec-2022

Answer:

Yes, however you will need to manually set the appropriate settings within the inverter manually, and run these batteries in an open-loop, voltage control based configuration.

Question:

Can the SOK server rack batteries be positioned vertically; either on their ends or sides?

Answer:

In certain applications, Yes! We have a full page in the instruction manual dedicated to this question. You can check it out here: https://www.currentconnected.com/sk48v100/manual-2-4/

Question:

What is the stud size on the terminals? 1/2"? 3/8"? Can't find this info in your online manual.

Answer:

Great question! They are M8x1.25 - for a ring terminal it would be best to use a 5/16" diameter terminal. The recommended torque for tightening these terminals is 20 Ft-lbs
