Re ESS setup with mulitplus 2 with VE configure 3
1: to setup all the settings do you need a Venus unit to set the mode 2 and 3? as the VE config 3 won't do it.
2: I am using the AC2 output as is were my PV inverter is hooked up to as per 28/05/18 document.
3: I can't get it to charge at all during the day at all with full PV inverter power export back to the grid, it shows as a negative VA on the VE bus monitor, which is correct. so what conditions need to set to make it charge?
4: So at night time it wont self consumption just stuck on the grid input only. latest ver of VE config3 and inverter firmware etc Unit firmware is 2625430 and VE config3 90.04.206.
5: I have ask the dealer, they said they were hard to setup and didn't know enough about it, or help.

ESS (Energy Storage System) (size:1632)
*) System uses Gel or AGM batteries
*) The battery capacity of the system is 40 Ah.
*) Sustain voltage during the first 24 hours of sustain 46.00 V.
Sustain voltage after 24 hours 50.00 V.
*) Cut off voltage for a discharge current of:
0.005 C= 48.00 V
0.25 C= 46.60 V
0.7 C= 45.60 V
2 C= 44.80 V
*) Inverting is allowed again when voltage rises 1.20 V above cut-off(0).
*) The solar converter will start reducing its output power at 50.20 Hz.
Output power will be reduced to minimum when the frequency is 52.70 Hz.
The converter will disconnect when the frequency is higher than 53.00 Hz.
*) Total installed PV inverter power is 2000 Watts.
Total installed PV panel power is 2000 Watts.
