    Growatt SPF 3000TL LVM Fault 08: High Bus Voltage

    Hey does anyone know how many batteries are wired together here? And whether they're in series or parallel? I want to make sure I have the correct number specified in my growatt settings. Thanks! For your entertainment, my guess is: 1 battery in series.

    Is My Battery Toast?

    I got my "80% charged" by just seeing what the Growatt was showing for the battery voltage (26.6V) under no loads. Under no loads, having it show 26.6V and then 26.1V 12 hours later (Growatt was turned off) is how I'm concluding that my battery is having problems. Guys, assume I know nothing...

    Is My Battery Toast?

    Thanks, I've lowered Fv to 27.6V

    Is My Battery Toast?

    The Growatt shows battery voltage while it's powered on.

    Is My Battery Toast?

    Charge and Floating voltage are both set to 28.4V.

    440W X 3 in parallel. The Growatt often throws a high bus voltage error on sunny days, even after adding a switch to remove 1 of the panels from the array on sunny days (but I use all 3 on cloudy/overcast).

    Is My Battery Toast?

    Hi Everyone, I bought a "160ah" Lithium battery that has been underwhelming in terms of performance, and I'm wondering all of your thoughts on how I should proceed. Throughout the summer, the battery was just able to make it through the night, but it couldn't handle the load put on it by my...

    Thanks, do you have a suggestion for what I should set my voltage cutoff to?

    Growatt SPF 3000TL LVM-24P - won't turn on

    @ger164 thanks for sharing those pics and description - did you get things working? Question for everyone - if I were to buy a couple 12v batteries and wire them in parallel to get to 24V, could I use those to "jump start" my Growatt? My big battery still dies overnight, and on a sunny morning...

    Growatt SPF 3000TL LVM Fault 08: High Bus Voltage

    Hey Guys, I hope you're all doing well! Here's an update: I've switched to 3P and I'm no longer experiencing "Fault 08 (high bus voltage)" but the system is still not running as smoothly as one would hope, I'm having to flip the Growatt's on/off switch several times throughout the day because...

    Growatt and 3 12v 30ah AGMs?

    Thanks ya I think I'll just sit tight until the big boy is back - didn't realize I was in "things might blow up or light on fire" territory, and I certainly don't know enough not to be a danger to myself and my shed :P

    Growatt and 3 12v 30ah AGMs?

    Thanks for the reminder! This scares me a bit. It sounds to me like running a 24v Growatt with 12v batteries is just a bad idea in general, probably best to just wait until the big battery is back in business.

    Growatt and 3 12v 30ah AGMs?

    Yep I'm in for some limping! When you say "turn off" do you mean at the power switch or should I disconnect the batteries altogether? I've noticed that "turning off" the Growatt at the power switch stops it from producing AC but it remains on if there's solar. Then it powers off once the sun...
