Inverter issue - urgent help required

[Dellmassive]

thats right - not regularly.

but now and again is fine,

and in fact its good to do it every couple of months to keep the calibration in check.

as all batteries self consume power by the BMS that is not accounted for.

++++


what normally happens is you check the battery . . . the BMS says its 100%,

then you camping and the following morning the battery is dead flat... to 0%. or very low voltage.

Every day's a school day. I'll try that once we're home.

Thanks Lee

Quick update:

Today, drove 1¼hrs to St Michael's Mount; parked-up for 5 hrs (bright, cloudy, limited sunny intervals); drove back to campsite.

Monitor is now showing 100% SOC/ 13.57v resting voltage. With some brightness forecast for tomorrow am/early pm, that should see us through to Wednesday morning when we'll be packing-up.

Once home, l'll have a conversation with VisionTech and do some further digging.

Thanks to all for the advice, suggestions and offers of assistance - much appreciated.
