Солнечная система контроллера

MCU and professional software are used as the control center to fulfill intelligent system control, along with PWM high efficiency charging way. Boost, recovery and float charging auto work for battery long-life and with temperature compensation. It has high accuracy over discharging control by the discharging rate, over-discharging control voltage modified by the battery discharging rate curve. Our controller has the function of self protection from overload, outside and inside short circuit, reverse connection, thunder and lightning, PV panel reverse current, over charging and discharging etc. During the short circuit and overload protection, no any component will be damaged and need change, including fuse. The LED will indicate the working state of the system in charging, overcharging power full, power low, over-discharging, over load, out short circuit, load on/off and etc. Our products meet the industrial production standard with wide temperature running area -35°Cto +55°C. In order to make sure the control accurate and reliable we use flash memory to save all work control point instead of adjustable resistance to project the control work point from going off as the adjustable resistance value is easily changed by temperature and vibration. And our products are easy to operate, robust in design.SpecificationsTypeSDCC-10ISDCC-15ISDCC-20IRated charging current10A15A20ARated load current10A15A20AWork voltage12V; 24VOver load, short circuit protectionOver load protection action: 1.25times rated load current in 60-sec, 1.5 times rated load current in 5-sec; Short circuit protection action: 3times rated load currentNo load current<=6mACharging circuit voltage drop<=0.26VLoad circuit voltage drop<=0.15VOver voltage protection17V, x2/24VWork temperatureIndustry stage:-35°Cto +55°CBoost charge voltage14.6V; x2/24V(keep 10-min) (Only applied when overdischarge appears)Direct charge voltage14.4V; x2/24V(keep 10-min)Float charge voltage13.6V; x2/24V(keep working until drop to the point of charge return voltage action)Charge return voltage13.2V; x2/24VTemperature compensation-5mv//2V(Boost charge, Direct charge, Float charge, charge return voltage)Lower voltage indicate12.0V; x2/24VOver discharge voltage11.1V no load-real-time modified voltage by the discharge rate; X2/24VOver discharge return voltage12.6V; 2/24VControl modePWM charge modesize of the installing hole :Size: 140 90.5(mm)Length between installing holes:133.5X70(mm)
