I asked this on another a few days ago.I’m in Melbourne with a 41kWh Fox ESS. during my 3-hour free electricity window the battery was only charging at about 3.7kW .? Melbourne, not the moon. anyone else seeing the same thing?
Old old former colleague Nokia in Melbourne, 41kWh Fox system.Ast week during his 3-hour free electricity window it was sitting around 7 degrees and his charge rate dropped to 3.7kW. Big battery, tiny sip. Window closed before he got to 30%.
Then I saw this SolarQuotes article about Fox ESS in Australian winter . Apparently Melbourne having a cold morning is now enough to turn some batteries into sleepy little bricks. Even better, some owners are apparently wrapping batteries up like they’re sending them to Falls Creek for a ski trip. Fox’s own UK guidance also warns that improper insulation could affect heat dissipation, accelerate degradation, or even lead to thermal runaway — while basically saying the owner assumes the risk. Beautiful. Very reassuring. Very “please DIY a puffer jacket for your battery, but don’t blame us.”
I am extremely glad I didn’t choose Fox.Checked my SigenStor app this morning out of curiosity. Charging at full rate. 7 degrees overnight.When I picked SigenStor the built-in heating pad felt like a “nice to have” detail at the time.Boring spec sheet detail when I was shopping. Less boring now.
Now? In Melbourne winter? It feels less like a feature and more like basic adult supervision.
Anyway, shoutout to my friend. Hope your battery gets well soon.
