hola
i am expat in a very sunny part of spain trying to reform a house as eco as possible.
Have acquired 7 pv panels 240Wp and enecsys microinverters.
Not running yet due issue with enecsys are gridtie which is the nub of being here.
Prefer micro as further panels may not be same. planning for 24v flooded batteries for night use in a bunker to keep them cool.
Have lots of open rustic land so panels are ground based, at 40m from house then to dedicated consumer unit ( not grid connected) with 30m x 10mm pvc cable from bunker to c/u.
part of house is on grid but very onerous in spain to go gridtie ( will avoid the politics of that)
No other power source but maybe 24vdc diesel gen later
How do i get micros to juice the consumer unit? ie. with a separate small inverter 12v to 240v to trick them into gridtie.
An alternative, because there is not a shade issue could acquire a second array on a string MPPT charger to batteries with an offgrid inverter for battery source being coupled to C/U.
Can the second array/battery inverter then trick the micros to output their 240v as well. How well would they couple together especially the offgrid inverter as it is not expecting existing 240v on its output side and effect on frequency.
So not yet having a second array how do i get the power of the sun to reduce my dependence on shafters Iberdrola at 20 cents per unit + the brownouts
