How to set Apex300 grid input to less than 10A

Product Discussion BLUETTI Apex & AC Series

Just got my Apex300 B300k and 2 x B300 system set up, upgrading from a AC300

One thing that I noticed is that I cannot set the grid input current to anything less than 10A on the Apex 300 (the range is 10A-50A), where the AC300 was running at 6A before. I need to set the grid input to lower as the wiring on this circuit can only support limited capacity as there are other loads on it. My EV’s inverter can only support 800W so I can only run 6A from that as well. Is there a way I can set a grid input current to anything less than 10A? The AC300 allows for it, can the Apex 300 also to?

Hobotech showed in the app he charged it all the way down to 1 amp. Go into pro mode in the app. He said the password is all 8’s.

That’s what I thought too! Things must have changed since Hobotech reviewed it.

I eventually found a way, but is super hidden.

If you go to adv, max grid input current, that menu only allows you to adjust between 10-50A, even in pro mode. If you want to go lower than 10A, then you have to go back to the settings menu → charging mode then select “custom” at the bottom. This will enable an extra mode which allows you to set between 1 to whatever setting you set in the max grid input current.

Hi Matthew, are you now able to successfully customize the current of APEX 300?

Why does it go up to 50A? I am in the UK (240V) but wouldn’t that be 120V x 50 = 6000 watts which is not possible so why does the slider go that high? Would be more sensible to have 3 - 30A range in the main menu.

Yes, I am able to adjust the charge rate using the app. However, the function is not easy to find.
You cannot adjust it on Setting>Adv>Max grid input. If you go there, the range is 10-50A. You must instead go to Setting>Charge Mode and then click on the small “custom” text on the bottom middle, which then opens the custom charge option, there you can adjust it from 1-10A. My suggestion would be to allow it to be adjusted from 1-50A on the Setting>Adv>Max Grid Input menu. Also, make the custom charge option visible by default on the charging mode selection along side silent/standard/turbo

The 50A max is for US/CA market or other markets where the voltage is 110-120V. I would assume the max grid charge current is less in EU or other 220-240V markets
