Hello folks,
I’ve set my H1-5.0-E with 5 HV2600 to 85% max soc, but with all this glorious sunshine it’s still going to 100%
Have I read correctly that the max soc setting only applies to grid charging? And if I have, does that mean when charging from solar it’s always going to 100?
Is there anything to be done about that if one wants it to go to 85%?
Many thanks!
Mark
Hi, yes MaxSoc only limits grid charge, it will still charge to 100% by solar.
You could switch the inverter workmode into feed-in first which exports everything after the house load is met, but there’s no way of setting a schedule so that at 85% it switches to feed-in so you would have to guess the timing.
Only thing to add is that it does no measurable harm charging the battery to 100%, and it is warrantied for 90% depth of discharge (10% minSoC is mandatory) so best to leave the system to do it’s thing… or if you add a home assistant (via modbus) you can get much finer control of the inverter (but you would need at least some computer skills and spare time)

Many thanks for the insight Dave, that's really helpful.
Luckily I have time, computer skills, and an already running HA installation. I might do some coded fettling (or might just leave it as is!)
On the 10% MinSoc, I have 'off grid' set to that, but on grid set to 20%. During the summer it's getting nowhere near that (most days the floor appear to be 45%). I presume this is all perfectly acceptable working for these batteries anyway?
Cheers

If you don’t have the EPS system wired (critical power in the event of grid failure) you can leave both minSoc’s set to 10% as you don’t need to reserve any for the EPS.
It’s more important the batteries get to 100% than down to 10% but always good to occasionally cycle them completely so the BMS can reset both of it’s limits.
If you’ve got the time/experience connect up the modbus you won’t look back, the data and statistics alone make such a difference and with automations you can do just about anything you want with the inverter - control charge or discharge power, change workmode on SoC and/or time of year etc… the only warning is that it’s a bit of a rabbit hole you’ll find yourself in once you have it
