The reliable family runner to GivEnergy’s all mod-cons sports car
The quick chippy tea to GivEnergy’s three-course dinner
The own brand to GivEnergy’s known brand
But make no mistake about it
We still provide a cracking battery storage system that works a treat.
We’ve just cut back on the bells and whistles to give you the most affordable alternative possible.
You’re getting a great product, for an affordable price, within a simple package.
So, which brand should you go for?
Polar ESS vs GivEnergy.

In general, Polar ESS is for you if:
You want a low-cost energy storage system that does its job simply and well
You’d prefer to leave your batteries to just do their thing – without spending time managing, monitoring, and continually fine-tuning your setup
You’re not especially fussy about slight variations in performance and access to premium features
You don’t mind waiting up to a couple of hours to get an email reply from support
