Charge controller technical specifications

Between the PV panels ("rough" DC current) and the battery ("smoothed" DC current), there has to be a charge controller to:
  • protect the battery from being damaged, and to
  • ensure optimal current to charge the battery.

A wide variety of types are available, from very cheap to quite expensive. Prices also vary widely between 10 Amp to 80 Amp controllers.

In most cases, the more expensive Maximum Power Point Tracker (MPPT) type is more desirable. It delivers an optimum DC current from the PV panels to the battery, even if conditions vary widely.

MPPT Solar charge controllers

  • Tracer-BPL series MPPT solar charge controller combines solar charge controller and LED constant current driver into one unit. It has multiple load control modes which are ideal for various solar LED Lighting applications, especially when a dimming function is needed. This series adopts the advanced MPPT (Maximum Power Point Tracking) charging methods which will results up to 30% charging efficiency increase compared with the PWM charge controllers. Thanks to the RS485 communication, the Tracer-BPL has the ability to realize remote monitoring via IoT.
  • XTRA(10A~40A) series is advanced maximum power point tracking (MPPT) charge controllers for off-grid photovoltaic systems, with optional display units (XDB1/XDS1/XDS2). It is designed according to the international standard with higher quality, reliability , and safety. The limitation function of the charging power, charging current, and automatic power reduction function fully ensure stability when working with oversize PV modules(max.1.5 times of rated power) and operating under a high-temperature environment.

 

LS-E (EU) Series solar charge controller

  • LS-E(EU) series is a reliable, stable, and economical solar charge controller, easy to operate. Based on the LS-E series, the LS-EU series adds a +5V/1.2A USB terminal output which can charge mobile phones, power DC fans, and other DC electronic devices.

 

LS-B Series solar charge controller

  • LS-B series is a common positive PWM charge controller. Thanks to the RS485 interface. The parameters can be configured via com. Port, APP, and PC software. It is widely applied to solar home systems, and surveillance system, etc.
