Quatro 15kVA inverter
with four 250/100MPPT’s as DC coupled
20kWp Pv array
and sixteen 3000UC Pylontec batteries
with ESS setup.
The South African Grid is not reliable and this system is used for critical safe installations.
The constant Load is aproxamitaly 3000Watt including radios and Airconditions.
Remote monitoring is not posable.
The site is quite remote and about 150km from civilisation. Frequent visits are difficult.
When the battery is at 100% or close to 100% the inverter makes a strange sound
the Output Power Dip
and the system returns to Grid feed for a few seconds
then Dip again.
I have tried all modes of ESS:
Keep batteries charged
Optimise with battery life
Without battery life
I set the grid ref to 100W , 500W and 1000W
Grid feed is not allowed
The entire site is on the Quatro Inverter
The Inverter is set up as energy meter.
