MPPT 100/50 Sometimes won't start charging in the morning

Given you’re troubleshooting I would avoid using VE.Smart Networking all together for now. It just adds another element into the system.

Once we are certain that everything is working perfectly at a hardware and basic system level, then consider re-activating the VE.Smart Network features.

Or maybe you do not need them at all.

Will do.

Hi @guystewart,

Unfortunately this issue has returned and I am now 100% confident that it is a firmware issue with the VE Networking.

Since getting the new 100/50 the system has worked flawlessly. As I stated above, the new 100/50 was showing it was receiving “Battery Current” under the VE Networking. The 100/20 did not show this anymore in it’s VE Networking dialog.

About a week ago I decided to upgrade the 100/20 to a 100/30 MPPT. I removed the 100/20 from the system. I added the 100/30 to the VE Network.

Unfortunately the very next day, the 100/50 did not start charging with exactly the same symptoms already mentioned previously. Once I removed and readded the 100/50 to the VE Networking, it started charging. I also note the “Battery Current” is now not showing in the 100/50 VE Networking dialog but it does in the 100/30. After a couple of days it failed again to restart charging in the morning.

The battery settings across the two MPPT’s are set exactly the same.

Can this please be investigated further.

Thanks,
David
