The 10 Best Solar Charge Controllers For Solar Panel Systems

1-RENOGY Solar Charge Controllers

Renogy Tracer 4210 40 Amp MPPT Charge Controller, 12/24V 100VDC Input (Lawn & Patio)


Description MPPT circuit solar controllers are considerably more elaborate than PWM. The voltage of the solar panel changes with time of day and temperature. The optimum voltage for battery charging changes as the state of charge of the battery. The MPPT charge controller matches these voltages and can result in 30% more efficient transfer of power. This means good MPPT solar charge controllers can reduce the number of solar panels needed by up to 30% – a tremendous benefit. While only a small part of system price, a MPPT solar panel charge controller can leverage the rest of the system to better performance. Specifications Negative grounded Nominal System Voltage: 12V/24V Auto recognition Max. PV Input Power: 400W (12V), 800W (24V) Rated Charge Current: 40A Rated Discharge Current: 20A Max.

3-SOLAR EPIC Solar Charge Controllers

SolarEpic MPPT 40A Solar Charge Controller 150V PV input Tracer 4215BN


If you need to monitoring the solar system or setting the controller, you may have to buy a MT-50 remote meter separately.

Description
The Tracer-BN series controller is for off-grid solar system and control the charging and discharging of the battery.
The controller features a smart tracking algorithm that maximizes the energy from the solar PV module(s) and charge the battery.
At the same time, the low voltage disconnect function (LVD) will prevent the battery from over discharging.
The battery charging process has been optimized for long battery life and improved system performance.
The comprehensive self-diagnostics and electronic protection functions can prevent damage from installation mistakes or system faults. In addition, the Tracer-BN series controller has a RJ45 interface to allow communication with other accessory.

12V/30A 400W MPPT Solar Boost 3000i Solar Charge Controller SB3000i


Blue Sky Energy’s Solar Boost 3000i solar charge controller charges 12V batteries at up to 30 amps from conventional 36 cell 12V PV modules. Patented MPPT technology operates the modules electrically in a manner that harvests all available PV power and can increase charge current up to 30% or more compared to conventional PWM type controllers. The voltage step-down operation of the MPPT power converter also allows use of higher voltage lower cost 60 cell grid-tie PV modules at up to 22 amps of output current. The process of converting the much higher 60 cell input voltage down to battery voltage may produce a charge current increase approaching 200%. Solar Boost 3000i’s sophisticated 3-stage charge control plus auto/manual equalization optimally charges flooded, GEL and AGM lead-acid chemistry batteries. A user configurable auxiliary output is also provided which can serve as either a 20 amp LVD load controller, 20 amp lighting controller with LVD, or 2 amp auxiliary battery charger for a second battery such as the engine start battery in an RV. The low power LED display combines excellent readability with very low power consumption, includes an automatic night time diming feature and may be turned off completely if desired. The high accuracy display shows battery voltage, input & output current, auxiliary battery voltage, and computes total solar charge amp-hours produced. To provide optimal charge control for various battery types all digital setpoints for charge control and load control are user adjustable.
