Attention (Wiring & Use)
- ALWAYS connect battery first. Make sure enough batteries’ voltage let controller recognize the right system voltage. NEVER connect the solar panel array to the controller without a battery. The disassembly sequence is contrary to the wiring order.
- DO NOT connect any Inverter/ wind/ Alternator or Charger into the charge controller. Please connect the Inverter directly to the battery.
- Ensure solar input voltage higher 3V or more than batteries’ voltage and total input power in the range. If input power is too low for max input power, it may be appears to have been discontinued, the charging current almost be zero when controller is floating charge.
- The charging indicator is on and off, and the charging current is off and on. This situation generally occurs on cloudy days or in the evening when the light is insufficient, which is a normal phenomenon.
- When the controller is buzzing, it is because the fan is trying to dissipate heat. Please wait patiently.
- DO NOT install the charging controller in direct sunlight to avoid power loss due to overheating. Remove all clutter around the controller to reduce interference and make sure there is enough space for heat dissipation (leaving a space of approx. 20cm).
- Ensure all connections going into and from the controller are tight. DO NOT let the positive (+) and negative (-) terminals of the battery touch each other.

Details
AP-SERIES MPPT controllers cover 20A–120A options for a variety of off-grid and backup solar charging setups.
Clearly labeled terminals help simplify wiring for PV input, battery charging, DC load output, and optional WiFi monitoring.
The built-in LCD provides at-a-glance operating data including PV voltage, charging current, battery status, energy totals, and temperature readings.
Designed for 12V/24V/36V/48V battery banks, with up to 150VDC PV input and optional app monitoring.
Port labels and front-panel buttons make setup and monitoring straightforward, including RS485 and a temperature sensor interface.
Multiple battery profiles are available, including LiFePO4, AGM, GEL, flooded, lithium, and a user-defined setting.
A typical hookup routes solar panels to the PV input, charges the battery bank, and powers DC loads, with optional WiFi monitoring.
Well suited for home, RV, and remote-site solar charging where reliable battery management is required.
Overall size is 573 × 365 × 195 mm; package includes the controller, temperature sensor, and user manual.
