Power battery when charge from grid
Hello, I have a Inverter Model: H1-5.0-E-G2
At night, when grid rates are cheaper in Portugal, I take advantage of the opportunity to charge the batteries via the grid. I've noticed that the charging power is always the same, i.e., it constantly charges at 0.83 kW. Is there any way to change this value? Thank you.

Re: Power battery when charge from grid
On your Force Charge schedules leave your minSoC set at 10%, as you have set it (75%), the batteries will only charge at 5A (DC) rather than the full power available using the Force Charge.
Re: Power battery when charge from grid
Dear Dave Foster, I have it at 75%, because if this value is below the battery value, I simply don't receive power from the grid. Example: if the battery is set at 22% and the minSoC is at 10%, I don't receive power from the grid. If I increase the minSoC to 30%, I receive power from the grid and it stops when the battery reaches 30%. Could it have something to do with the firmware?

Inverter Hardware Version : -Master : 1.26Slave : 1.02Manager : 1.42
This is my inverter information.
Re: Power battery when charge from grid
For some reason the normal force charge isn’t working, but the low power charge is - it’s probably best to start by getting your firmware updated as it is very old, latest Master is 1.45 and Manager 1.62

Once you have the latest firmware we can then walk through the inverter settings that could interact to slow down your charge rate such as ‘maxchgcur’ and ‘importlimitpwr’ - both of these can effect the charge speed.
Re: Power battery when charge from grid
Well, this is my devices firmware;

Inverter:
version_master - 1.26
version_slave - 1.02
version_arm - 1.42

3 batterys EP5:
version_BMS - 1.003

I see that there are issues in version manager (version_arm) 1.62.
Which versions do you recommend upgrading to in my case for all devices?
That is, which versions are most stable for my case.
Thank you

I think they are the latest firmwares, I downloaded them here on the forum

Latest version has lost force discharge workmode from scheduler, if you do use that workmode, the best version to load for now is Manager 1.58, Master 1.44
Re: Power battery when charge from grid
And as for the batteries, should I keep the same version or update to 1.008?
Thanks in advance

The latest versions are essential for the 'warm' EP variant that has the internal heater but there are also several fixes so it is well worth updating to that.
Re: Power battery when charge from grid
Okay, last question.
How do I upgrade?
Is it possible to do it from there?
Thanks in advanced
Re: Power battery when charge from grid
If you have installer access you can do it from the Foxesscloud website, otherwise it has to be done by either your installer or request the upgrade from Fox service.
