SunGoldPower SPHXX048 All-in-one Support

[jtubb]

I got my hands on a manual and took a stab at making a config. Looks like an expanded SRNE device. This config is working for my SPH8048. One improvement would be to change the enum for Device State [0x0210] based on Device Type [0x000B] to improve compatibility with other models. I'm not sure of the "right" way to do this so I'm ignoring it for now.

Writes work, but for certain settings I needed to issue a "reset" command (1 written to 0xDF01) for them to take effect. When in parallel all settings should be written to the device with modbus address 1 and that inverter will replicate settings out to the rest. The reset can be done on any of the inverters, and they all start working with the new settings.
