A list of compatible batteries for FoxESS hardware

H or AC Series inverter:

• HV2600 (requires a BMS)

• ECS 2900/ ECS 4100 (BMS is built into the master, cannot mix 2900 with 4100 systems)

• FoxESS Mira HV25 (requires a BMS)

AIO (All In One) Series inverter:

• HV2600 (requires a BMS)

Generic Inverter i.e Solax Or Solis:

• LV5200 (Not compabile with FoxESS inverters!)

Hi,

Is it possible to use both HV2600 and Mira 25 on the same inverter?

Hi
Can I use one master ECS 2900 battery without slave?
Are the ECS 2900 V1 and V2 compatible i.e. Master V1 + Slave V2?

No minimum spec is 1 master (ECM2900) + 1 slave (ECS2900)

You have to use all V1 for V1 ECS2900 and all V2 for ECS2900-2

Are there any 3rd party batteries compatible with the Fox ESS H1-5.0 inverter?

Or more specific: is this battery compatible:
Pylontech US3000C
3.2kWh capacity per cube.
I would need 3 modules (9.6 Kwh)

If not, which Fox ESS battery (batteries) would you recommend (need ca10 kWh)

No there are no 3rd party batteries readily available, the Pylontech batteries are low voltage and the Fox ESS batteries are a high voltage system.

Probably the best value battery circa 10kWh is the Fox ESS EP11 which is a 10.36kWh LifePo4 battery (90% of which is usable) in a single cabinet (it is heavy at 100kg), you can scale them up to a maximum of 4 batteries if needed which needs an additional junction box to add more than one battery.
