    600VDC PV Disconnect - Switching of both +ive and -ive required ?

    We have two strings of nine panels coming to make a total of 18 420WAA Pure R REC panels for a rooftop array that will be connected to a 100A 600V Schneider Charge controller. Each string operates at NOTC at almost 500 V and around 7 amps, so combined would make 14 amps. There will be four...

    High Efficiency N-Type (TOPCon) or Heterojunction Panels Available in North America?

    Although seemingly more efficient and durable, n-type panels don't seem to be widely available in North America (Canada specifically). N-Type panels went into large scale production a few years ago and seem destined to eventually supersede PERC panels as the panel of choice. N-type...

    Low surge, energy efficient dishwashers for off grid use?

    Running a near new, free back alley find nice Kenmore (Sears Canada brand) dishwasher our neighbours ripped out during a kitchen rebuild. Works perfectly in our off grid cabin, except: Large motor starting surge means it won't start on either our Honda 2200i or HondaEu3000 with eco mode on...
