Hi Mikem664,
I have several mates that installed large NiFe battery banks & run there air-con all night long when needed.
Two of these have;
- 40x 1.2V x 500Ah =24kWh energy storage.
- 40x 1.2V x 1200Ah cells =57.6kWh.
Both have UPS inverters & Charge controllers.
The first guy, is on-grid, but uses a Green bio-gas generator that auto starts (AGS) if/when the batteries trigger low voltage & then switches off as programmed, the other guy is a stone mason & lumber jack that uses a lot of energy, they live off-grid.
So, I understand the bottom line with energy storage is the kWh of Energy you have Stored!
Unless someone can correct that.
