lights on MPPT charger working in ESS

System is a 3phase on 5 MP-IIs with one EasySolar-II DX and additional SmartSolar MPPT 150/35.

Lights ( bulk/abs/float) on MPPT does not mach the lights on MP-II.

Does this matter?

They will be externally controlled by the system. So it should not matter.

If they were using their own charge algorithm then you should see the different stages.

That what I was thinking, but why light are not indicating the same state on MP-II and MPPT? The MPPT lights should indicate the same charging method as MP-II if MPPT is externally controlled?

The GX device is the device reporting what state the system is in. The rest of the systems are slaves.

Also technically if you are feeding back into the grid they will always be working and therefore always in bulk. The bulk abs float cycle is amperage based.

In a non ess inverter system all the states are shown.

Hi @Alexandra ,

My system is ESS and MP-IIs are now all showing "Float" but MPPT shows "bulk".

If MPPT is "externally controlled" shouldn't it also show float?

My MPPT is feeding the grid, but its light not always showing "bulk". Sometimes "Abs" is on.
