Re: Battery pulling down panel voltage???
@Virtuousdesires There are a couple of advantages to MPPT controllers, but neither may apply in your application: 1. You can use higher voltage panels, which tend to be bigger and more costly to ship…1 · -
Re: 24v, 12v, Panels, Charge Controller and Battery
Another factor is distance to array. For longer runs, using an MPPT controller allows for more panels in series, higher voltage, lower current, and thus smaller wire.1 · -
Re: Maximum charging voltage for 8 bateries 12v200ah from 8 solar panels
As noted, in your application a lower low battery cut-off may work better. Your pump likely draws a very high current for a short time to get started, then drop off to the rated current as it continu…1 · -
Re: 24 volt battery chargers in 2017?
The only thing I can think of to try is to check the connection between the charger and the al1 controller. I remember back in the dialup modem days that crud and corrosion on rj11 were sometimes the…1 · -
Re: small, inexpensive solar heat pump idea
In summer, when you really want AC it could work out better than a straight south array. AC could run longer and keep space cool vs shorter and have to make space cool.1 ·
