Frequently Asked Questions

The Aspire 11KW takes up to 3500 W of PV array.

Peak efficiency is > 97%. Whatever is not converted leaves as heat, so the Aspire 11KW needs clear air around it and a mounting spot that is not the hottest wall in the building.

It carries an IP20 rating. That is the only ingress figure published for this unit, so read it against the spot you mean to mount it in rather than assuming shade is enough.
