Charge batteries from excess solar

Hi there

I’ve just received emonpi board today had little problem getting the image flashed and reading my solar export but now need to use this data

I’d like to capture some of the excess energy in batteries in the process of harvesting 18650 cells to make the store

Any advise on how to drive the charger or charge reconstruction would be good

I’m thinking some form of node red combination but never used it before

There are some mentions of battery charging here, did you search the forum?


I do something similar. I tried a number of different ways and found NodeRed by far the easiest way. The first thing you need to do is get your solar export input publishing to NodeRed. From there you can make decisions when to switch the charger on and off. For that part of it you will find help on the NodeRed forum:!forum/node-red
