Hi,
I have two Apex 300’s with each one B300K in parallel via the Hub A1. No solar panels as of now, simply a cleaner/quieter option to the generator during outages for the house.
I also have a Firman 10000/8000watt gas generator (specs attached) which we’ve been using to feed the house via a manual transfer switch (30A) during outages.
Until I replace the generator with an Inverter Generator later in the year, can I safely recharge the Bluetti setup using the 120v plugged into our current Firman generator?
If “yes”, is it best to use the A1 power cord (will it spread the charge to the other Apex & batteries or would I need to charge the Apex 300’s/B300K’s individually?
And finally, if “Yes” would I need to make any adjustments in the app?
Thanks in advance.
Info I neglected to include would my sub-panel is only a 30A.
Seems I’m finding my own answers.
The manual for the Apex 300 does say:
“4.2.5 Generator
Connect the Apex 300 to a gasoline, propane, or diesel generator using the AC charging
cable. The charging stops automatically when fully charged.”
However it includes a note:
“Notes:
• Make sure the generator delivers a pure sine wave output with matching voltage
and frequency.
• Ensure the generator’s output power exceeds the Apex 300’s charging requirements.
• It’s recommended to enable the Grid Self-Adaption mode when charging the
Apex 300 with a generator.”
It does look like I’ll be needing to change/upgrade my generator to an “Inverter Generator”.
Cheers!
It would be interesting to see your results using your existing generator, with “Grid Self-Adaptation” mode enabled - maybe it will work? Maybe not?
I won’t try UNLESS I get a green light from Bluetti if I use the Grid Self-Adaptation mode rather than risk voiding my warranty. I’ve got more than a few $$ invested at this point. lol
But if I do get the GA… I’ll be sure to post here. ;)
