Hi there,

 

Similar question to the above but my battery is smaller. Can I install 2 * MKSII 48v inverters on 1 * 4.8kw 100ah Narada Lithium Iron Battery? I would like to do this to increase the peak load capability of the system

 

Regards

I should have mentioned last post that I was only answering whether sharing the battery was appropriate in any circumstances. Not whether a 7.4 kWh battery is sufficient for two inverters.

100 Ah is already a bit small for one inverter. 200 Ah is recommended, though that's likely assuming that they are lead acid. But for two inverters, especially if the aim is more peak load capacity, I think 4.8 kWh (100 Ah) is too small. The BMS will likely only allow about 1C, which is 100 Ah, which is less than 5 kW after losses.
