Solar Charge Controllers is a premium solar PWM charge controller that includes a full electronic visualization of system essential details that works as a user-system user interface that allows the setup of the solar motorist.
Suitable for 12 and also 24 volts batteries, an automatic find feature recognizes the battery voltage upon initial connection as well as offers up to 30 amp charging existing. Built-in circuit protection includes overload, short circuit, reverse polarity, lighting/source, PV panel reverse-current, overcharging, and discharging security.
The controller consists of a battery temperature level sensing unit (BTS) that ensures temperature compensation of the fee voltage enhancing battery performance as well as life and decreasing battery maintenance.
The enclosure is constructed out of resilient plastic with visual LCD graphic symbols to supply condition indicators of cost, battery condition, and also system faults. P30L fits as the perfect model for the well-known solar package for a RV of WindyNation.
Best Solar Charge Controller – Buying Guide
The type of the solar charge controller refers to whether it’s an MPPT or PMW model. MPPT controllers are widely accepted as being the very best of the very best, so they naturally leading our list. However, we have actually also consisted of in our rankings a few PWM controllers as premium options are occasionally preferable for those seeking to create straightforward systems to power solar lanterns in a yard or a smart phone.

2. Amp Rating
The first thing you’ll intend to take into consideration is the amp rating. This dimension tells you the highest possible amperage the product can output to the batteries. As an example, if you have a solar charge controller with a 10 amp rating, it wouldn’t be a great fit for 2 100 watt photovoltaic panels with a power of 6 amps.
You see your panels would combine to produce 12 amps complete as well as the controller can just result 10 amps. Because of this, two amps would wind up not being utilized, which’s not what anybody desires. Instead, you intend to pick a solar charge controller with a rating that’s 25% higher than your solar panel’s peak power.
