If a panel puts out 2 watts or less for each 50 battery amp-hours, you probably don't need a charge controller. Anything beyond that, and you do. Solar charge controllers play an integral role in solar power systems, making them safe and effective. You can't simply connect your solar panels to a battery directly and expect it to work.
Use our MPPT sizing calculator to find the model that suits your needs. In our model names, the first number represents the maximum PV open circuit voltage, and the second is the maximum charge current. The smartest solar charge controllers under the sun deliver lightning-fast, 98% efficient performance.
MPPT charge controllers are highly recommended for most large solar power systems. PWM charge controllers are typically only a viable option for portable applications such as for RV trips or possibly for a small off-grid cottage.
If your battery banks are some distance from your panels, running the system at higher voltage and relying on MPPT solar charge controllers is the best way to cut down transmission loss. Can You Use More Than One Charge Controller?
What Are Solar Charge Controllers? The charge controller in your solar installation sits between the energy source (solar panels) and storage (batteries). Charge controllers prevent your batteries from
