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. 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)

Main matter in this product page: We Manufacture , Supply , Install highly efficient Solar Street Lights of two categories : Solar Integrated / Solar All-in-one Street Lights : These are Solar All-in-one lights which means LED s , Solar Panel , Lithium (LFP) battery , Charge controller , BMS ( Battery Management System) , PIR (Motion Sensor) are inbuilt in one single unit Ranges available from 15 watt to 100 watt Solar Semi Integrated lights : These are Solar Street lights on which Solar Panels are mounted separately on top of pole with help of mounting frame and remaining components like LED s , Lithium (LFP) batteries , Charge Controller , BMS ( Battery Management System) are kept in one single unit . Ranges available from 15 watt to 60 watt Description / Features : No External power supply from DG set / EB line is required to run these lights they are completely self powered Comes with 5 years complete warranty including battery pack They come with back up of 18-20 hours a day and designed to operate in all climatic conditions with minimum back up time of 14-15 hours a day. No External cables required cable cost will be completely saved Saves Fuel cost / Energy cost these assemblies generally gets breakeven in less than 2 years Auto Dusk to Dawn Operation is programmed Auto On-Off of lights sensing ambient light Equipped with highly efficient LiFePo4 Lithium batteries and they has cycle life of 5000 cycles Highly efficient and tier 1 grade MONO PERC Solar Modules are used PIR (motion) sensor can be equipped as per requirement and they sense motion from distance of 10 meters. Completely safe to use at construction sites since no cabling and cable routing are required and they are complete DC systems .
