I have two Genasun MPPT boost solar controllers (I really wish Victron had a boost solar!) which I would like to "monitor" within the Victron ecosystem. I know I can put a smart shunt between them and the battery and get the information I'm looking for (mainly the current they are supplying), but since they will output a maximum of ~10A a 65A shunt is overkill and $$. Are there any other solutions that will integrate with Victron that are smaller & cheaper? (I don't have a Cerbo right now, but will be getting one in the future...)
