Compatibility between batteries

I have an off-grid system composed of:

PowerACU 7.2 MAX Inverter and one battery Pylontech US2000 (2.4 kw)

I know one battery is not enough and I'm planning to purchase at least another 2-3 starting with one this month. The problem is I can't find a US2000 model, I can only find US2000C model and I don't know if they're compatible (the US2000 and US2000C models).

Thank you for your help!

People do mix pylon batteries. Each model has an operation/installation manual, some times (if you can find the latest version, and model depending) they have guidelines for mixing. Different firmware can play a part.

The most important is usually to make sure they are all properly charged and that the new ones are master.

You can always contact their support and ask for guidance.

The 5000 series manual, for example, states the following:


Compatible with the US3000C, US2000C, US3000, and US2000.

*Mixture using master battery priority: UP5000>US3000C>US2000C>US3000>US2000
For same type of module always use the latest production unit as master. *Mixture using battery deployment option:

Master battery (1st) Slave 2nd ~8th Slave 9th ~16th
