I already have a growatt solar inverter so i am looking for a "battery inverter" which i can control via RS485.
This is the first one i see..
Does anyone know other battery inverters (so only battery connected to it) where the output can be regulated?
The number of units that allow external "user" control of the output are very limited because most country grid codes actually stipulate a requirement for this not to be possible. There are real particular reasons for this but mostly protectionism at this stage because the number of units on the system is very very small.
The GTIL units should be possible to control if the firmware is opened up with the right messaging (waiting for someone to discover the messaging).
SolarRiver inverters are controlable on the output but the response rate is not really much use for load matching and then your reducing solar output, unless your feeding them with 400V DC from an inverter board through a regulating capcitor.
Otherwise I have done many hours research and browsing trying to find the unicorn of a high output capacity, low losses, reversable, user controlable inverter. The closest I got to was to look at disconnecting the grid altogether and mixing a few inverters... and is the plan for 2022.
