Solplanet ASW S-G2 and ASW LT with GridZeno.
A grid inverter without a battery. GridZeno shows the solar production and lowers the inverter's output at negative prices. Applies to ASW1000-6000-S-G2, ASW5000-10000-S, ASW LT-G2, LT-G2-Pro, LT-G3, 75-150K-LT and 250-360K-HT with Ai-Logger.

How the inverter is controlled
A grid inverter without a battery: GridZeno shows the solar production and lowers the inverter's output 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 output is set quarter by quarter by the selling price, but only where the installer has turned the limit on. Solplanet's limit applies to the inverter's whole output, not just the sale to the grid. The dongle sets the installer's value back afterwards.
- Grid and consumption
- Not shown. A Solplanet grid inverter has no energy meter the dongle can read.
- 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.
What is special about the Solplanet ASW S-G2 and ASW LT
The model code 1-5 in 31073 is a grid inverter. The dongle doesn't tell the ASW S-G2 from the ASW LT/HT: input 1000 says whether it's three-phase, and the number of MPPTs in 31074 how many of PV1-PV10 are added up.
- The grid
- The dongle can't read a meter through the logger, so grid and consumption aren't shown.
- The sun
- The sum of the strings, with the inverter's AC power (1370) as the floor. At most ten PV inputs are read.
- The Ai-Logger's software
- From 006R the limit is controlled through the inverter's 45403. An older logger gets the limit through its own 60003, which applies to every inverter on the logger.
- The large models
- On the 150K-LT and 250-360K-HT the logger is called Ai-Logger 2000. Write to us before you connect the dongle, so we can confirm it.
How it differs from its neighbours
- Solplanet ASW grid inverter with RS485 cable: With an RS485 cable straight to the inverter, the dongle reads it without an Ai-Logger.
- Solplanet hybrid: The hybrids behind the Ai-Logger have the model code 11-16.
From the dongle's firmware and our notes on each inverter, not from the datasheet.
How to connect the dongle
Over your network, without a cable to the inverter. Approx. 15 minutes.
- Connection
- Solplanet Ai-Logger (Modbus TCP, port 9999)
- Where
- Solplanet's own logger, which is connected to the inverter with RS485 and to your network. The GridZeno dongle only needs power and network.
