GO-WM-LV 5.1-7.7-10.2_GoKWh Wall-Mounted Battery Storage


1. Can I expand the GO-WM battery retrospectively?

Yes, our GO-WM series of energy storage systems have a total capacity of 5.1,7.7 and 9.6kWh. With the same capacity, up to 15 battery modules can be connected in parallel if you need.

2. Where should GO-WM battery be installed in my home?

Generally, any wall in your home will do.

But try to install the battery in a ventilated and dry place, avoid contact with fire and water. Also pay attention to the load-bearing capacity of the wall, so as not to overwhelm the wall and cause it to collapse.

3. What material does my GO-WM energy storage battery use? Why use it?

GoKWh’s GO-WM series products use LiFePO4 batteries as raw materials. The battery composed of LiFePO4 material has long service life, long cycle, large discharge power, high stability, high-cost performance and is very friendly to the environment. The life cycle of each battery can be recycled more than 3000 times and used for about ten years. In the past, the cycle life of our commonly used lead-acid battery was less than 400 times, the service life was about two years, and the volume was large and bulky. In contrast, the performance of lithium battery is better than that of lead-acid battery, which is a new choice for people to buy batteries.


4. What’s the deal with battery lifecycle?

Our engineers ensure that lithium-ion batteries installed in GO-WM series can withstand up to 6000 cycles! This will allow you to use one battery much longer than other manufacturers. And up to 10 years of superior design life to provide your family with cost-effective energy storage solutions.


5. Do I have to buy a special inverter before installing GO-WM energy storage system?

The GO-WM ESS series with the high compatibility BMS, seamless butt joint with energy storage inverter(SMA, Victron Energy, Deye, Goodwe, Growatt, Sermatec…)
