Hi Everyone I have a Kool Energy 1.5Kw lithium battery unit. I have 2x Canadian Solar 410 watt panels connected to it in series. The load on the unit day and night is a router and 2 x laptops, so very light load. Strangely enough during the day when there is PV power available the unit switches off about 30 minutes after loadshedding has kicked in, however during the night loadshedding the unit does not switch off. The errors that is received is E06 Battery voltage is lower than shutdown voltage and E10 low voltage of battery. The state of charge is indicated as 100% in all instances when the unit switches off. The spec's of the panels are Optimum operating voltage 31.2 V Optimum operating current 13.15 A Open circuit voltage 37.2 V Short circuit current 14.01 A The range of input voltage DC of the Kool Energy is 35 - 100 VDC. Has anyone else experienced this, and what can be done?

Thank you everyone for the responses. Modina, I will go and check that out.

We have this very unique problem with an installation. Sunny Island Sunny boy combination with a lithium battery. When loadshedding starts i.e the municipality switches off the power, the Sunny Island goes into standby mode. This happens every time when loadshedding starts. Then a manual switch on from standby is done and everything runs perfectly fine. When we switch off the main breakers in the DB or even at the electricity at the meter, or any trip switch prividing power to the Sunny Island, the Sunny Island switches over to battery and runs perfectly. This also happens everytime. Sunny Island was replaced under warranty, battery was replaced under warranty. We had second opinions from electricians confirming there is no wiring issues, but still the problem persists when loadshedding kicks in. SMA confirmes the settings are 100% fine. Has any other installers had this very unique problem? Could it perhaps be in the way that the municipality switches off the grid versus a main breaker switches off the grid?
