Inconsistent is the best words I can use for this.
Looks cool. Sounds great. Performs terribly. In a singular configuration.
I only have one.
I have a 6KW inverter and a 5KWH battery that should work?
Correct me if I’m wrong! Please!
I learn more and more about how much these batteries…
I found out an older model growatts bms can get locked in a potentially dangerous situation and only a growatt engineer can unlock it!
How convenient.
I went to bed last night with %50 SOC.
I was pulling 50 watts from the battery from 12-8
Total 8 hours.
400wh should’ve been depleted from the battery when I woke up if my math is correct.
The growatt axe is a 5KWH battery @ %50 SOC= 2.5KWH?
Right?!?
In theory I should’ve woken up with say %37?
I woke up and everything was off and I’m back to square one.
Pre charge circuit issue?
Bms locked?
I called Signiture solar whom in purchased the battery from and they told me they have absolutely nothing to help me.
Q-do you have a way to access the battery monitoring system? rs485-usb?
A=no
Q-so no one can actually see what’s going on inside this battery.
A=growatt hasn’t provided us with any trouble shooting for this battery.
Q-can you forward me to the return department.
A=yes
I told them I’d like to return the battery.
They said okay lemme call you back.
Never did…?
It’s been a wild ride so far with the growatt battery. I don’t know if it’s battery error or user error? No way to confirm ?
Wasn’t even shipped with a manual?
I’m about to buy two eg4 batteries instead and I’m excited to see how that goes.
