Weight: 6.12 lb Item Description 100A MPPT charge controller: 4-level battery charging algorithm for fast, efficient, safe charging (bulk charging, boost charging, float charging and equalizing), 100 amp rate charging current. High efficiency: The solar controller adopts the latest optimized MPPT technology, which can quickly track the maximum power point of the photovoltaic array in any environment and obtain the maximum energy of the solar panel in real time. The photovoltaic utilization rate is ?99% and the maximum efficiency is ?98.1%. Can be used in a wide range of applications, such as solar RVs, solar household systems, etc. Multiple protection: The solar charge controller is compatible with 12V/24V/36V/48V batteries and has short circuit protection, open circuit protection, reverse protection, and overload protection. Intelligent MPPT algorithm improves system efficiency, three-stage charging optimization and extends battery life. Wide battery compatibility: 100A solar controller is compatible with 12V, 24V, 36V, and 48V photovoltaic systems, and can automatically identify the system voltage, with a maximum charging current of up to 100A; supports a variety of lead-acid batteries, including flooded, AGM, GEL, lithium-ion battery LCD display: The display of the 100Amp solar controller can clearly see the operating data and working status. With LCD display and 4 buttons, it is convenient to dynamically display system data and operating status.

Don't connect inverter, wind, alternator charger into the charge controller! Please connect the solar controller to the battery. If solar PV input voltage lower 3V or lower than batteries? voltage. It may be appears to have been discontinued. Parameter Setting:Floating voltage Low voltage reconnect Low voltage discharge. When controller makes buzzing because the controller dissipate heat. It will be stop when temperature return to normal. Don't let the positive (+) and negative (-) terminals of the battery touch each other.

Users should first connect the battery before connecting the solar panel for the solar controller to function properly.Otherwise, it may cause irreversible damage to the controller. Why is there no voltage displayed after I connect the solar panel? It may be caused by low voltage. When connecting the PV, it is necessary to ensure that the PV voltage is 1.5 times higher than the battery voltage. Why does my controller display a current of Zero? When the battery is in float charging state or the solar panel is damaged, the charging current is problly to be less than 1ah. When the charging current is less than 1Ah, the charging current is displayed as ZERO. What you can get when you buy a POWLAND MPPT solar controller?
