SolaX Triple Power Battery Balancing

[spacemoc]

There appears to be a lack of information available on how to properly balance SolaX batteries. Here are the steps:

1. Force discharge the batteries down to 10%.
2. Shut down the master battery and disconnect the slave battery.
3. Short the master battery, then reconnect it to the inverter and power it back on. You should see a state of charge (SOC) on the inverter that is significantly higher than 10%.
4. Discharge the master battery down to 10%.
5. Once complete, reconnect the slave battery and return the system to normal operation.

At this stage, both batteries should be at the same SOC (10%).

However, there is one issue: the master battery will not operate without at least one slave. So, how does one balance the master and slave when only two batteries are available?

Not familiar with these batteries, but I would be rather surprised if the master cannot work alone.

Question is what does it mean: short the master battery?
