Product Description
The SANDI solar charge controller adopts advanced digital control technology, touching keys and automatically operation. With the features of PWM (Pulse Width Modulation) battery charging and unique control technology, the PV charge controller improves battery life efficiently. The PV charge controller is only suitable for controlling solar modules. Never connect any other types of charging source to the controller. This can destroy the controller and/or the charging source permanently.
To meet different solar power stations' need, there are 48V,96V,120V,192V,220V,240V, 360V,384V,480V,492V and 600V other normal series voltage level base on different battery voltage of off-grid PV power station system project.
The PV charge controller is a smart device which designed for off-grid PV power system. It has great running performance with LCD display and convenient operation. The controller also automatically control cell cut or connect ordinarily according to the change of battery voltage.
The charge controller is very important for solar power system, the performance will affect the life of system directly, especially the battery life. Anyway, the battery's life will be shorted when battery being charged or discharged. The SANDI series PV charge controller adopts PWM charge model which can improve battery life greatly.
Product Feature:
1, The solar controller uses high performance 32-bit chips which is excellent EMC design
2, The controller adopts advanced PID algorithm which has more accurate battery energy management system to improve the battery efficiency 45% at least
3, The controller adopts three charging stages (buck charging, equalize charging and float charging) which can maximize the utilization of photovoltaic modules and batteries
4, IGBT Modular design ensure stable and efficiency performance of solar controller and solar power system
5, The controller has perfect battery protection function and with multi-stage charging technology to improve battery life 35% at least
6, The controller has double loop control function of voltage loop and current loop, user can set the limiting charging current
7, Fully enclosed duct design and high-speed fan for cooling makes the controller working under harsh environments
8, The controller has power generation statistics and real-time power curve function, so we can know power generating information at any time
9, Colorful LCD display, touching key and multi-language option makes the HMC (Human Machine communication) easy and convenient. Users also can set working parameters through the LCD panel and touching keys according to different battery feature
10, The controller also has temperature compensation function and RTC real time clock function,
11, Standard Modbus protocol for RS-485 or GPRS communication to extend the communication distance (optional function)
12, The patent of second protection function which can protect battery from over charging due to power switch failure (optional function
