If a device is not in the library yet, we build the template for free as soon as we have the register data.
Use cases
- Record serial number and firmware versions of every inverter in your fleet for service and warranty.
- Check after a change from the portal that the work mode and minimum SOC really took effect.
- Compare the export limit and grid code of all sites to spot a wrongly commissioned inverter.
- Get an email when the work mode changes, for example after someone adjusted it on the inverter.
Installation
Connect the RS485 lines of the inverter to A and B of the ModbusCloud Gateway, with termination at both ends of the bus.
In ModbusCloud, add a Modbus RTU device on the Gateway with 19200 baud, 8N1 and the inverter address, and import this template.
Import the SolaX X3-Hybrid G4 template on the same address for live values and writing.
Check that the serial number and Work Mode show the values you see on the inverter display.
Things to watch for
Why are there two templates for one inverter?
The inverter reads settings on one set of addresses and accepts writes on another set with the same numbers but a different meaning. One template cannot hold both, so live values and writing are in SolaX X3-Hybrid G4, and reading back the settings is in this template.
The charge period times look wrong.
Times are packed into one register, one byte for the hour and one for the minute. For the read registers the minute is in the high byte, for the write registers the hour. Read the raw value as high byte x 256 + low byte and compare it with the inverter display.
Some registers stay at 0 on my inverter.
Registers marked X1 only apply to single-phase models, and lead-acid, generator, dry contact and parallel settings only matter when that function is used. BMS slave versions and serial numbers stay empty when fewer battery modules are installed.
