MPP Solar Inverter

This Enapter Device Blueprint integrates MPP Solar inverters working in parallel mode. The blueprint supports WatchPower protocol over RS-232 communication interface.

For detailed connection and operation instructions check our Watchpower Solar Inverter Monitoring guide.

Connect to Enapter

• Sign up to the Enapter Cloud using the Web or mobile app (iOS, Android).
• Use the Enapter ENP-RS232 or Enapter ENP-KIT-232-485-CAN communication module for physical connection.
• Add communication module to your site using the mobile app.
• Upload this blueprint to the communication module.

Physical Connection

For physical RS-232 connection with the inverter you will need:

• RS-232 communication module:
  • Either Enapter ENP-RS232 communication module,
  • Or ENP-KIT-232-485-CAN module (check out UCM Kit introduction and simple JLPCB ordering guide) + ESP-32 development board.
• Communication cable with RJ45 connector on one side and plain wires on another side. You can use RJ45 breakout connector to assemble such cable.

Troubleshooting

• _Single mode detected alert means that this blueprint doesn't support inverters working in single mode. Please upload this blueprint.
• Check the wiring according to the diagram above.
• Check communication with inverter using official Watchpower/Solarpower software. If it works, then this blueprint should work as well.

Notes

• Voltronic Axpert MAX 6.5KW and 7.2KW a are parallel models according to documentation. They can't use single mode Blueprint even there is only one inverter in the setup.
