Hi all
I have:
- 1x Quattro 48/8000/110-100/100
- 1x CCGX
- 2x Solar MD 3.7 with DataloggerV2
- 2x Solis 4kW G4 1ph Grid-Tie Inverter, each with a ET112
- extra ET112 for measuring AC-OUT2;
I want too:
- See power output on essential and non-essential loads on CCGX and VRM;
- be able to close the relay on AC-OUT2 in an off-grid environment (load shedding) and power non-essential loads if there is enough power available from PV;
- In On-grid periods power both AC-OU1 and AC-OUT2 with PV first;
- Only charge batteries from PV
I want too see who has done something like this, and get feedback and collaborate please.
Issues arrived:
- Will the Solis inverters give an error during in off-grid if a CT clamp is configured? The theory is it should use the CT clamp during on-grid and frequency shifting from the Quattro during off-grid to regulate power output. Was advised it should not give an error, will give feedback, we are close to powering up the PV;
- Since i started this post some feedback came back, Solis said there is a 'Fail-safe - Disabled" i have to select to avoid this error;
- I am using ESS, so non-essential loads is displayed as next to the grid with an icon on a CCGX, which is fine. Please correct me if i am wrong, but my understanding is that ESS wants to only use AC-OUT1 with a ET112 on the grid input, so all power via inverter will be considered essential loads, and the difference between that and the meter, will be displayed on non-essential loads. Since my requirement is to power AC-OUT2 loads in daytime and if the PV is strong (still not sure how we will be configuring this, will get to it later) I had to connect the non-essentials on AC-OUT2 instead of leaving it on the DB as the manual suggest. My biggest question is how do i program the CCGX to display the AC-OUT2 on the CCGX/VRM with a ET112? The only options are inputs (Grid, Generator and PV Inverter, the last one i will be using for the Solis PV Output).
- Assistance to program the Quattro to only charge batteries from PV;
- I found assistance to program AC-OUT2 to close during Off-grid here: https://community.victronenergy.com/questions/1343/enabling-multi-ac-output-2-during-grid-outage.html
I did possibly miss something in the manuals, so please just direct me to the correct one should that be the case;
