  • New Solar Power System for Remote Monitoring

    I am in search of equipment to power a Cell Modem (1.25A@12VDC) and a Pump (1.1A@12VDC).

    These will be running outdoors in a plastic waterproof tote, 24 hours a day, 7 days a week, all year in Canada.

    The setup I have now is 4x105 Ah AGM batteries, 2x180W 35 V panels, 2x20A PWM charge controllers. The batteries are wired in series-parallel (24 V) with a 24 V inverter. The summer is easy but during the winter months the batteries need to be changed out with charged batteries every week or two.

    Now I need to make a couple more of these set ups and I want to do it right. I am looking for quality manufactures of batteries/panels/MPPT charge controllers and what would be the most efficient, particularly in the winter months. I am definitely not an expert at this stuff so any help or recommendations would be greatly appreciated!

      If your equipment is DC powered, why do you need an inverter; that sort of thing can be very
      wasteful of your precious energy? Bruce Roe
