Remote firmware update of MPPT 100/20 via Raspberry PI CCGX

Hi everyone.

I have a Smart Solar MPPT 100/20 charger connected via VE direct to a Raspberry PI based CCGX.

I would like to remotely update the MPPT firmware via the CCGX. The CCGX is powered via the output of the MPPT I plan to update.

My question is, will the MPPT update complete before there is any disturbance to the load output? Which would impact the updating.

Or do I need to have the CCGX on a power source that is not driven by the output of the MPPT it is updating?

It is at a remote site and I was hoping to avoid going there to complete the update.

The MPPT is on currently on v1.53. Every night just as the last bit of solar voltage drops off the panel, the load output very briefly turns off and back on. I think this is a bug now fixed in v1.54 which was just released.

Thank you


James

Hi,


According to the developers, the load output will (unfortunately for you) turn off during a firmware update.


Kind regards,

Thank you for letting me know. I suspected that was the case after watching the charger behavior during a previous update via bluetooth. But I didn't have another unit I could test with.

I will change the power supply configuration for the PI hardware on the next site visit and move it away from the charger load output. Then I have options in the future.

Regards


James
