How to do with solar energy?

[LolDeibid]

Hi all,

First i have to thanks to all of the developers. After 1 year of use i couldn't be happier.

Now a friend just get a Leaf and he has solar power energy at home. My software version is an old one and i know that the latest version allows to setup with solar, but... how it works? I can't find where to connect the sensor box or if i need to do something special, i just know that i can select "solar mode" =/

Can you please help me??

Regards!!

Hi!

There are pins on the connector named "RS485 A B 12V GND". The SmartEVSE communicates over Serial Modbus with the Sensorbox or another modbus power meter.

I've actually connected a sensorbox on that pins, to measure all my consumption at home. The sensorbox is connected to the main phase (monophase). If i want to add solar panels to my installation, where should i connect the sensorbox?? or i would need to use 2 current transformers? Regards, David.

The Sensorbox 1 or 1.5 can only measure the current, not the direction of the current flow.

Sensorbox 2 can do this, as it has a separate voltage input, to determine the direction of the current. (phase difference)
It needs to be connected to the same main phase wire, as with the sensorbox 1.

So the current sensor (CT) doesn't need to change, just plug it in the sensorbox 2.
