We are still having some issues and are looking to improve them. Our batteries are dying in some locations that are getting a lot of cloudy weather. We are using 100w solar panels now. Bigger solar panels are not much of an option, as they take up a lot of space. I am thinking lithium batteries...

I am looking for a switch that will switch between two batteries. We have a small sound monitoring system that is powered by solar. To ensure it always is working, it would be great to have a protection switch. My idea is: If the voltage on battery A gets too low, switch to battery B. This...

Ok interesting, we didnt consider a smaller battery could actually help us. I dont think we would want to go too small, as we want to have enough power in case of longer periods of cloudy days and such. So I guess we will look into how large of a solar panel we can go with, if we could fit a 200w.

Our studies are not typically in the middle of winter as there are acoustic reasons (and logistics reasons) we dont want to do them then. But still can get cold in late fall/early spring. I was thinking with insulation in the battery box, and the heat the gear produces, the heater shouldnt need...

Fair point, perhaps we should measure them with a multimeter to get a more exact current figure. These systems were already made when I joined the company, but I helped improve them by adding the cellular routers and cleaning up some of the wiring. Some of our equipment varies, as dose the power...

Not entirely sure - never measured it. But doing an indoor test the equipment seemed to last for around 1.5 weeks with no solar panel attached, with a fully charged 100 ah battery. Yeah, was thinking we could get some 100 W rigid panels. I dont think they would be a ton bigger which is good for...

Hello, I work for an acoustics consultant firm, specializing in environmental (outdoor) noise. We are based in Wisconsin so it can get cold. Our current setups consist of a RIGID plastic toolbox with an AGM battery to power our equipment (sound level meter, sound recorder, ultrasonic anemometer...
