Packaging Details : Solar Battery Charger is an electronic device that uses solar photovoltaic (PV) energy to charge batteries safely and efficiently. It regulates the voltage and current coming from solar panels and ensures batteries are charged without overcharging, overheating, or discharging.

Solar home lighting systems

Telecom towers

Street lighting systems

Solar UPS/inverters

Remote industrial equipment

EV and surveillance systems
Working Principle
Solar panels generate DC electricity from sunlight.

Charge controller manages the flow of electricity to the battery, avoiding overcharge.

Battery stores energy for later use (typically during night or cloudy conditions).

Optional: DC loads (lights, sensors, etc.) or inverter for AC output.

Types of Solar Battery Chargers

PWM (Pulse Width Modulation) Basic controller, slows current as battery nears full charge
MPPT (Maximum Power Point Tracking) Advanced type, maximizes power from panel even in variable light
Smart Solar Charger IoT-enabled, app-connected, multi-stage charging
DC-DC Solar Charger For direct DC output to devices or systems
Hybrid Inverter/Charger Combines inverter + solar charger + grid charging

Main Components

Solar Charge Controller Regulates voltage & current to batteries
Solar Panel Input Accepts voltage from PV array (12V, 24V, 48V)
Battery Bank Output Connects to lead-acid, Li-ion, or tubular batteries
Display/Indicators Shows charging status, fault, battery level
MPPT Tracking Circuit (optional) Boosts performance 1530% over PWM

Compatible Battery Types
Lead-Acid (Tubular/SMF)

Lithium-ion (LiFePO, NMC)

Nickel-based batteries (less common)

Chargers should be selected based on battery voltage (12V/24V/48V) and chemistry (to match charging profile).
