¡ÜA built-in maximum power point tracking algorithm can significantly improve the energy utilization efficiency of photovoltaic systems, and raise the charging efficiency by 15% to 20% compared with the conventional PWM method.
¡ÜThe product boasts an optimum MPPT tracking efficiency of up to 99.9%.
¡ßAdvanced digital power supply technologies raise the circuit`s energy conversion efficiency to as high as 98%.
¡ßDifferent charging program options including those for gel batteries, sealed batteries and open batteries, customized ones, etc. are available.
¡Ü The controller features a limited current .charging mode. When the solar panel power exceeds
a certain level and the charging current is larger than the rated current, the controller will
automatically lower the charging power and bring the charging current to the rated level.
¡Ü Instantaneous large current startup of capacitive loads is supported.
¡ßAutomatic recognition of battery voltage is supported.
¡ßWith defective LCD liquid crystal display, convenient user to identify system failure.
¡ßThe controller employs a built-in over-temperature protection mechanism. When temperature
surpasses the set value, the charging current will decline in linear proportion to the
temperature and discharging will be halted so as to curb the temperature rise of the controller,
effectively keeping the controller from being damaged by overheat.
¡ßFeaturing a temperature compensation function, the controller can automatically adjust
charging and discharging parameters in order to extend the battery`s service life.
¡ß0 v lithium-ion batteries charging function.
¡ßUse a metal shell, heat dissipation performance is better.
¡ßSolar panels charge high input voltage, reduces solar connection wire specifications, reduce
the system cost.
¡ßCan support Rs485 protocol model of choose and buy, meet different occasions communications needs.
Protection function is introduced
¡ßWaterproof
Waterproof level: IP21
¡ßInput power limiting protection
When the solar panel power exceeds the rated power, the controller will limit the solar panel power under the rated power so as to prevent excessively large currents from damaging the controller and enter into current-limited charging.
¡ßPhotovoltaic input side too high voltage protection
If the voltage on the photovoltaic array input side is too high, the controller will automatically cut off photovoltaic input.
¡ßPhotovoltaic input side short-circuit protection
If the photovoltaic input side gets short-circuited, the controller will halt charging,and when the short circuit issue gets cleared, charging will automatically resume.
¡ßPhotovoltaic input reverse-connection protection
When the photovoltaic array is reversely connected, the controller will not break down, and when the connection problem gets solved, normal operation will resume.
¡ßLoad short-circuit protection
To load short circuit timely fast protection and open automatically after a certain time delay trying to load. When. a load short circuit, can be manually remove load short circuit.
¡ßReverse charging protection at night
This protection function can effectively prevent the battery from discharging through the solar panel at night.
¡ßTVS lighting protection.
¡ßOver-temperature protection.
When the Controller temperature exceeds the set value, it will decrease the charging power or halt charging.
