Solar charger Error code 87 - PV input shutdown, is it safe to disconnect solar panels?

Hi, I just got one of my SmartSolar MPPT VE.Can 250/100 rev2 into this error: Solar charger Error code 87 - PV input shutdown. First it got into Error 39, after minute it went to error 87. This MPPT has the latest Firmware (v3.13)

The documentation says I should disconnect solar panels. Just to be sure I have only PV fuseholders on these strings (no DC circut breaker). Is it safe to disconnect them now during day? Isn't there any danger making DC spark/welding?

I have measured voltage around 250 mV. But current is like 6,7 Amps. I have 6s2p strings with 410 Wp panels so for this MPPT it's 4,9 kWp.

In case my VRM ID: 48e7da8898eb Thanks!

Well it looks like faulty MPPT. After 750 kWh.

I disconnected PV array, measured everything... Hope to get warranty replacement soon.

Error 39 is the older code for the 87.

What were all the battery settings?

Did you reconnect and try again as per the instructions?

A dc disconnect would definitely be a good addition as well. Useful for maintenance purposes as well.

How did you get on? I've had the exact same issue this afternoon also with my SmartSolar MPPT VE.Can 250/100 rev2. Your case is the only one I can find.


I've tried resetting once without any success, I'll try again and also try turning it into standalone mode at the same time, but i'm not hopeful.
