Hi everyone, I’m writing to ask for advice/suggestions on how to configure the Bluetti Apex 300 power station as I need it :-) We’re talking about a farmhouse, two connected panels (about 350+350W, not in full sun), and everything is working properly.
What would I like to do? I’d like to connect the fridge to the Bluetti, and the Bluetti to both the panels and the mains (which I already have). This way—according to my idea—the Bluetti should power the fridge from the battery until the battery reaches a certain threshold (e.g., 30%). Then it starts charging not only from the panels but also (or exclusively) from the mains until it reaches another threshold (e.g., 80%). Then it disconnects from the mains and returns to solar.
The idea is to use it as a sort of backup for the mains: as long as the battery has plenty of charge (typically during the day), it uses the battery; when the battery is low (typically at night), it recharges from the mains.
I’ve tried fiddling with the app, charging modes, SOC modes, etc., but I can’t seem to get it configured the way I want. Even during the day, with a full battery and the panels in the sun, it uses a bit of mains power (and I don’t understand why, given that the fridge draws very few watts).
Do you think it’s possible to implement what I’m asking for? Am I missing the logic? Can anyone help me? :-)
Thank you so much!
Daniele

I think you want “Self Consumption” mode with a SOC threshold of 80%.
A few questions:
- when you say “it uses a bit of mains power” - how much are you seeing?
- have you fully updated the firmware?
- are you on 230V or north American split phase 120/240? (you say “mains” which sounds more like UK)
good luck in getting a straight answer from bluetti. I was going to spend about $10,000 american dollars for a parallel apex 300 setup and wanted it setup like you want which most manufacters refer to as battery priority. inverter runs off battery all the time…charges off solar and/or “mains” and for “mains” charging config for off peak charging. this is an advertised feature for the bluetti apex 300 and there are even charts of return on investment for various configs …so I asked bluetti various times for a list of everything needed and was told that the feature I was interested in was not supported.
so I bought an american setup that supports the feature with no proprietary componets…just the inverter, battery, and a few wires.
Hai ragione, sto scambiando mail con loro da settimane senza avere una valida risposta, pensavo fossero loro i maggiori esperti! Esattamente: io vorrei dare priorità alla batteria e farla caricare (tramite la rete elettrica nazionale) solo quando raggiunge una soglia bassa e quindi tipicamente di notte…
Hi, where can I find the “Self Consumption” setting in the app? I don’t see it…
I’ll answer your questions:
- For example, with the battery at 96% and solar panels in full sun, and only the fridge plugged in and turned on, the battery draws 49W from the grid and delivers 67W to the fridge via the AC output. This means it only uses 18W from the battery; I pay the rest to the energy provider!
- Firmware always updated
- I’m in Italy, I have a standard 220V outlet
Thanks!!
In my Bluetti app (iPhone, version 3.0.8, North-American split-phase 120/240V), I see this:
- click the AP300 link
- click the Gear icon to get to settings:
- scroll down to “Working Mode”
There you can choose Self-consumption and choose your desired SOC.
