Rolled my EB240 outside to charge with solar. I got the E021 code which basically says it’s too cold to charge. Rolled my other EB240 outside and plugged it in to the same solar array. Started charging without a problem. It was about 60 degrees F outside.
Rolled the EB240 inside the house and let it sit for a while. Plugged in the AC charger. Error code again. Is there a way to clear the error code or reset the unit? Unit still has two-bars of power. I was running it last night with a small space heater pulling about 500w.
Try letting it sit longer to fully warm up to the minimum temp and try again.
The unit was in the house before I took it outside. My other EB240 and an EB150 were charging fine. I’m in L.A. and it was about 60 degrees. For me that’s a little chilly but the other units were working fine. I’ll keep the 240 inside overnight and check it again in the morning. Thanks, Scott.
Low temp charging cutoff should not happen until around 0C. At 60F, that’s around 15C should be just fine. In fact it is ideal to charge batteries.
If those were your temps, I cant imagine temperature playing a role
Snowstorm & Scott: That’s what I was thinking as well. There must be something else going on. I remember seeing a post or thread somewhere that the EB240 can be reset but I can’t recall exactly where I saw that.
Sorry for the inconvenience.
E021 is the temperature protection. Pls put the EB240 in the room temperature, Turn off the unit now. Do not recharge the unit and do not use it to power anything. Turn it on when it is room temperature.
I let the 240 sit inside overnight. I plugged it into the AC charger and everything works fine. Error code is gone.
Thanks for everyone’s replies. Still kinda puzzled but glad it works!
Something does not add up here with the temps you reported but glad it works fine now.
I would not expect a temp protection error unless it is close to 0C or 40C.
Unless the temperature sensor is not reading accurately or there is more to the story.
The unit was outside on my patio and there was a steady breeze. It was charging initially but when I checked about an hour later the error code showed. Perhaps the wind chill on the aluminum case triggered the temp warning.
