EG4 24000 btu hybrid starts up and pulls both DC and AC for a brief time, then DC drops to 20 watts and bounces around between 20 and 50 watts. 8 450 watt panels supplying 390 volts hooked to unit. Unit works great on AC, but will not pull DC. Switch on AC limiter and DC shuts off completely. Purchased all from Signature Solar, spoke with customer support, they didn't like one ground connection, I fixed and now they will not answer the phone or return messages. Anybody have this problem with the DC not being used by the Hybrid Solar Mini-Split?
