Polar ESS

polar ess black

This is our budget friendly option, it might not have all the bells and whistles as its big brother GivEnergy products but that doesn't make it a cheap and nasty alternative, far from it
 
The first and most obvious difference is its modular design, there is no smart unit that you would want to put on show to impress the neighbours, it is designed to be functional more than aesthetically pleasing
 
Your system will be composed of 2 components, the inverter and the battery(s) , lets look at these in turn

The hybrid inverter.

 
  • A solar inverter and a battery inverter in one tidy little unit
  • Two power capacity options, to meet your power needs
  • Seriously high cost-performance ratio (aka, bang for that buck)
  • Can be installed nice and neat in a standard server rack
  • Loads of inbuilt safety features
  • Supports voltage balancing function during charging (or passive balancing for the techies)
  • Supports multiple parallel operations, so you can scale as you like
  • Displays key info like charging/discharging voltage and current via a handy digital screen
  • Harness up to 9kW of useful generation 
  • DC/DC charging from solar for maximum efficiency
