Fox ESS Solar Battery Reviews
Bought From: Aussie Batteries Show additional information
There were various reports about FoxESS not being reliable but further research showed it was heresay from installers with no experience in Fox and were pedalling much more expensive battery options with lesser quality battery cells, often a warranty that didnt cover the whole system or would only cover Cells and other parts for 2 to 3 years.
The Good:
FoxESS Battery cells are made by the same company in china who makes the cells for BYD, Tesla etc..
FoxESS is owned by a company who is the largest exotic metals processing plant in china.
The price is half the cost of other home battery systems.
It provides full home backup with solar charging during grid outages when DC Coupled (Up to 45.7amp for the 10kw inverter).
Availability was within a week for the KH10 single phase inverter and 42kwh battery
10 year warranty covers all of the battery and inverter.
The Bad:
Fox Support is based in China and communication is via very broken English
