Works: tested and measured on real hardware.

A grid inverter without a battery: GridZeno reads it and lowers the export limit at negative prices.

Battery

None. The inverter is a grid inverter without a battery, so there's nothing to charge or sell from.

Stop selling at negative prices

The inverter's export limit is set quarter by quarter by the selling price, but only where the installer has turned export limiting on. GridZeno only lowers a limit that's already set and never turns it on or off.

Grid and consumption

Requires a Huawei energy meter.

Manual

When the control is on Manual, the dongle changes nothing on the inverter. It reads, and if GridZeno has changed something, it puts the inverter's own settings back, including your own charge limits.

The model name in 30000 starts with SUN2000, and the dongle has read that there's no battery.

The connection

RS485 with the inverter's address, or 1 if it is 0.

No Smart Dongle

A Smart Dongle uses the same RS485 pins, and two masters on the same bus disturb each other.

Export limit

Through 47416-47418, when the installer has turned limiting on in 47415. If the inverter refuses 47415, the dongle promises no export limit.

How it differs from its neighbours

• Huawei SUN2000: With a Smart Dongle and a LUNA2000 battery, the battery can be controlled over the network.

From the dongle's firmware and our notes on each inverter, not from the datasheet.

Network cable with RJ45 plug. Approx. 30 minutes.

Port

RS485 IN

Pin

A at pin 1 (RS485A), B at pin 2 (RS485B), GND at pin 3 (PGND)

Where

On the underside of the inverter. RS485 IN and RS485 OUT are two waterproof RJ45 ports with the same pins. OUT continues to a possible next inverter.
