4 days based on 12 kwh Per day usage (500W)

8 days based on 6 kwh Per day usage (250W – Fridge /Freezer)


Due to the fluidity of Solar Panel stocks, we will provide between14kw to 15kW worth of solar panels currently on offer.

Battery Specs:

Can be discharged 100% without damage (provided they are charged back up within a few hours- just like Lithium, don’t leave discharged for prolonged periods)

Similar cycle life and DOD when compared to Lithium batteries (compare at DOD and cycle life graphs)

Lithium Batteries are unable to charge when temps are below 0C or 32F, or discharge below -22C, when used for cabins or exposed to the Elements nothing else works!

No Heating or Cooling required, No venting required, completely safe Non Hazmat Batteries

Developed for the Militarily in the 80S, this battery is immune to BMS failures, Unbalanced cells, temperature cutout etc.

You can remove one battery and start your Semi Truck in frigid conditions, and put it right back in your solar setup, no problem

Resistant to Explosion, Fire, Hot and Cold temps (-40F to 150F)  can be paralleled with Lithium batteries of similar voltage range (45 to 59V DC)

A 48kWH pack (50kwh Usable) consist of 16 pcs Silicate Gel 250AH 12V batteries

Negatives:  Batteries are HEAVY, 172 lbs each ( 2 man lift)

Can be arranged into a rack mount cabinet.
