Hi. My equipment is Multiplus 2 48v, Cerbo, 4 xn12v Lifepo in series, smart shunt.
I have the ESS assistant installed. I want to program it so it will only charge between a certain time. I have setup schedules charging and it goes from inactive to active on the menu tab when the correct time has arrived but its not charging the battery.
It looks like I have the same problem (Cerbo GX, Quattro and Pylontech US5000 batteries).
I have been using the ESS schedule to prevent battery use during the Octopus Go overnight period (00:30-04:30) for EV charging, which has worked fine to use grid instead of battery.
But last night, for the first time, there should have been some battery charging to reach 35%. You can see below that the level stayed at around 31% and no charging took place.
I'm not certain I have a major problem after all. I just tried setting a 10 minute window to charge the battery to 50% (currently at 31%) and it did start charging, whereas it didn't start charging to 35% from 31%.
Perhaps there needs to be a greater difference between the target and starting charge before charging begins? Although it would seem strange for software to behave that way.
I'll try setting a higher charge level overnight and see if that works.
Hi,
Start charging occurs if SOC is lower than (SOC Limit - 5%), SOC limit is to stop charging.
When it reach that value, due to the setting "Self consumption above limit = PV", it will continue to take from grid in mode "keep battery charged"
Thank you @jeanmarie, you've put my mind at rest. I don't think I can "accept" this as an answer, because the topic seems to be a different issue, but I certainly appreciate your help.
Hi you all,
And what about the following;
My setup is new (Easysolar GX with 4 lead-carbon batteries) thus the SOC is not yet matching the actual battery charge. It is hovering around 98% even when the voltage is 47V.
How to do a full charge (without interruptions) ? With the scheduled option this is not possible because it doesn't differ more than 5 percent
thanks
