Solar charge controller is the most important part of the solar system. It is too intelligent and automatically to control the charge, discharge and load of the system. The performance of the controller can influence the stability of the system, especially the lifetime of Battery.
30A 12/24V Solar Panel Battery Charger Controller (QW-SR-HP2430A)
Can be used for lithium batteries and with USB port. Charging program options forsealed, GEL and flooded lead-acid batteries and lithium batteries are available.
1. Product Introduction
This solar controller applies in solar photovoltaic systems, which coordinates the working of solar panels, batteries and loads. It adds some protection functions, so that the entire system can be in efficient and safe operation. The extremely low consumption makes this controller suitable for profes-sional applications in telecommunications and traffic management technology.
2. Features:
1) Except HP4830 /40, 12V/ 24 V system voltages are automatically recognized.
2) Charging program options for sealed, GEL and flooded lead-acid batteries and lithium batteries are available.
3) An upgraded 3-stage PWM charging algorithm is adopted. Application of an equalizing charge to the battery periodically or when over discharged, can effectively prevent the battery from non-equalization and sulfuration, thus extending the battery's service life (with the exception of GEL and lithium batteries).
4) With temperature compensation employed, charging parameters can be automatically adjusted (with the exception of lithium batteries).
5) A wide range of load working modes facilitate the product's application to different types of street lights and monitoring devices.
6) The product provides overcharge, over-discharge, overload protection, as well as short-circuit and reverse-connection protection.
7) By virtue of an advanced load starting method, large-capacitance loads can be started smoothly.
8) A range of parameter settings and power-down saving functions are available ,thus requiring no repeated setting.
9) The product provides a dot matrix graphic LCD screen and a human-machine interface with 2 keys.
10)The user-friendly design of browser and animation interfaces ensures convenient and intuitive operations.
11) (An optional communication function) provides a RJ12 data port (output of TTL /MAX232 /bluetooth signals), with the data adopting the standard Modbus protocol, and can be used together with our upper computer monitoring software.
12) Boasting an industrial grade design, the product can function well in various tough conditions.
13) TVS lighting protection is adopted.

4. What is PWM Solar Charge Controller
PWM stands for Pulse Width Modulation. PWM is often used as one method of float charging. Instead of a steady output from the controller, it sends out a series of short charging pulses to the battery - a very rapid "on off" switch. charger controller application
The controller constantly checks the state of the battery to determine how fast to send pulses, and how long (wide) the pulses will be. In a fully charged battery with no load, it may just "tick" every few seconds and send a short pulse to the battery. In a discharged battery, the pulses would be very long and almost continuous, or the controller may go into "full on" mode. The controller checks the state of charge on the battery between ulses and adjusts itself each time.
