The HCH1 will not work with a normal G1 Insight grid charger without modification, because the cooling fan requires a PWM signal to turn. Today, my eBay special PWM generator came in, and I will be incorporating it into my grid charger as soon as my replacement power supply comes in. This time around, I'm using a single 500ma Mean Well LED driver, with a 100-200v range. Charging should be slightly faster now, and should work on both really cold days (higher voltage) an from a deep discharge.
