I solved this with my 12 V system using a combination of batteries, inverter charging, and solar. If you set up a Venus OS system on a Raspberry Pi or Cerbo GX, you can use the large image with Node-RED and DVCC to automatically limit the charge current as voltage increases.
I’ve created a Node-RED flow that scales the charge current based on battery voltage — here’s what it looks like on a chart. The internal charger works alongside the DVCC setting to support the solar charger and maintain around 50 A of charge until the battery voltage rises, at which point the current is gradually reduced.
