We are about to move into quite a remote house which we know the area is effected by grid failure, plus i would like to be able to run mostly from a stored solar system. My intention for how i would like the system to work is that during the day, PV will charge the batteries and power any small loads (We will both be at work so don't expect much draw here). In the evening i would like the house to mostly run off the inverter and batteries. When/if the batteries get to 40% SOC, i would like it to swap back to grid power. (There is once sentence in the ESS that states when battery power is not available, the system will buy from the grid). I would also like this to be the case when the power demand exceeds the inverters capacity, i would like it to be either topped up or swapped over to grid power, is this possible?
If it gets to a preset time, say 6pm and the batteries aren't at say 60% SOC, then i would like to set a charge condition that the charger will kick in from the grid supply, in case of grid failure (I know this is possible from the ESS manual)
If grid failure occurs, and i discharge the batteries to say 10%, i would then like the generator to be auto started to charge batteries/run loads (Again im fairly confident from reading manuals that this is possible)
I don't intend on using the AC-OUT2 on the quattro as we wont have many non essential electric loads, No AC, Oil fired heating and hot water ect.
I have attached a quick diagram of my intentions below. To reiterate, i guess my main questions are;
If grid power is available, but the quattro is working from batteries, is it possible to set the quattro to power the loads from the grid once the batteries reach a set SOC? The ESS manual refers a lot to disconnecting loads at certain preset SOC's, but i just want it to power from the grid instead of disconnecting loads.
The second is in the case of overloading the Quattro inverter, when grid power is available. Will it top its current capacity up with grid power? Will it switch to purly grid supply instead and bypass the invertor all together?
Can the Cerbo and touch 50 run ESS? They arent mentioned as compatible in the ESS manual but i assume the manual is older than the products? Also, is it possible to run two touch 50 displays from one Cerbo? So i could have one by the setup in the garage and one in the house?
Thanks in advance
