Pren got a reaction from DaveAWalker in Using Pylontech US3000 batteries efficientlyToo many acronyms for a noobie....
Going to reset the SoC limit to 50% before going to grid today... that should balance using the batteries more efficiently, allowing some leeway if there is power outage, and preserving the battery life!

Pren got a reaction from Bigawatt in Using Pylontech US3000 batteries efficientlyReceived the attached Pylontech battery performance curves from Pylon support if anyone is interested...Seems like these batteries can be run hard (high DoDs) and still last for many years

Pren reacted to Louisvdw in Using Pylontech US3000 batteries efficientlyI have a 4kWh battery. My SOC limit is set at 40% and when we had load shedding the other day it went down to 30% using about 400W during that time. If you don't have mega loads (resistive loads) then 50% might be too conservative still for a 7kWh battery.
But look at your loads that you plan to use and check the values during the next loadshedding and then adjust accordingly for your setup.

Pren reacted to Youda in Using Pylontech US3000 batteries efficientlyPersonally, I'm cycling my US3000 stack between 100% SoC and 40%SoC. Once discharged to 40% SoC, my system automatically switches to the grid. Since manufacturer's specs allow cycling between 100% and 10%, I have a lot of margin here.
BTW:
Technically, it would be better to cycle these between 40% SoC and 90% SoC daily, while allowing a full charge (100%SoC) only once a week, to let BMS reset amphours counter and balance the cells. But as far as I know, no inverter on the market has ability to set such a complex rule.

just check the whole thread you will notice the reason for that short period:
@Pren mismatched DoD and SoC in his description. In reality, he's using just 1.4kWh out of 2xUS3000 and then he's switching to grid. Basically treating 7kWh of lithium like 7kWh of lead-acid
