Hi Dan, sounds like there might be a little issue there – although 2.9A per hour is quite a high draw for a fridge, our 200w blanket should still be able to keep up with it provided the weather is reasonably fine. Feel free to reach out to techsupport@hardkorr.com and the team can walk you through some troubleshooting. –Sam

Hi Wayne, you will always need a regulator with a solar blanket, although you may find that another device you are using already has an inbuilt regulator, for example your DC-DC charger. A 300w solar blanket will still be compatible with smaller deep-cycle batteries, check the battery’s specifications, it should tell you what the max charge current is. In ideal conditions a 300w solar blanket will be pushing in about 18A per hour – make sure this number is lower than your max charge current. –Sam

I have 3x 105 amp calcium deep cycle batteries in my camper trailer. My fridge draws 2.9 amps per hour. I have the hard korr 200w solar blanket with the 15 amp reg. I always seem to run low on batteries after two days. Is my solar blanket large enough to keep up with these batteries. I am also running the 4 bar light kit. Is it possible one of my batteries is in need of replacing? Or am I not putting enough charge into the batteries to keep up?

G’day Jeannette, for this setup to work you’ll need four things: a deep-cycle battery (to store power), a battery box (to connect 12v accessories to your battery and charge your phone), a solar mat or blanket (to recharge the battery), and a small pure sine wave inverter (to charge your laptop). A fridge will generally only consume about 2A per hour and it doesn’t take much power at all to charge your phone and laptop, so 200W of solar power will be plenty to keep this setup going. Hope this helps! –Sam

G’day Barry, yes that’s correct – the power station has an inbuilt solar regulator. –Sam

Thanks Sam for your prompt reply. I will order one.
