Good morning; Four days ago I have installed a TrakMax 30L Charge Controller to a 800AH Lead Acid Battery Bank and four 100w Monocrystaline panels (for a total of 400w) in parallel mode. The TrackMax 30L Controller detects 20.3 volts in peak hours, however it always shows a current of 0.0A from the PV array. The charge limit in the TrakMax 30L Controller is set to 30A. I have two additional MPPT Controllers (other brands) connected to separate 400W PV arrays charging the same battery bank and they are showing around 20.1 volts from the each PV array and current from 0.1A to 1.6A being delivered to the battery bank. Depending on sun power the controllers show the battery Bank charge ranges from 13.4 to 14.2 volts (so batteries seems to be almost fully charged). I have never seen any amperes being delivered from the TrakMax 30L Controller even when the other two controllers are delivering current to the batteries. System is 12 volts. I have two questions: 1. It is normal that the TrakMax 30L Charge Controller show 0.0A as current being delivered to the battery under this scenario, where other controllers are delivering current to the batteries? 2. The Charge LED in the LED Indicators area keeps "Blinking", not steady, during day when sunlight is present, and turns red during night, is it ok? Asking this because the TrakMax Users Manual does not indicate that this light must be blinking, but just yellow, in order to charge.
