Had informed me for a long time, with other providers either the inverter did not exhaust the full 600W or the collectors were not so efficient, or it was called for older collectors a higher price. The set from Sonnstrom is optimally optimized. When ordering, I was still skeptical because according to the manufacturer Heckert, the collectors were officially sold out for the year. The information and date selection for the delivery is super professionally designed and the delivery came as agreed quickly and on time. Now it is really fun to look at the energy meter, because
the system helps us as a family to reduce the next electricity bill.
I am already thinking about what we can expand solar.
