The Simtek MPPT Plus 120V 70Amp is a fully automatic hybrid solar charge controller for 12V and 24V battery systems. It charges your batteries from solar panels, and it turns to the grid when solar power falls short. You can buy it online at Roshanex in Pakistan.

Overview

The Simtek MPPT Plus 120V 70Amp auto-detects 12V or 24V charging mode on every startup, so setup is simple. A cooling fan controls the temperature automatically. When solar energy is not enough, the controller turns on the grid supply so the battery can still charge. As a result, you get steady charging through the day and into the evening.

Protection Features

Overheat Protection

If the temperature exceeds the safety level, charging stops. The red warning LED starts blinking, and a message appears on the LCD screen. Charging stays off until the temperature drops below the safety level.

High Voltage Protection

When the solar voltage exceeds 120V (Model #: 1224K27), charging stops. At the same time, the red warning LED blinks and the LCD shows a message. Charging stays off until the voltage falls below the safety level.

Overcharge Protection

When the battery voltage exceeds 15V in 12V charging mode or 30V in 24V charging mode, charging stops. The red LED blinks and a message appears on the LCD. Charging then stays off until the voltage drops below the safety level.

Battery Low Warning

When battery capacity falls below 20%, the red warning LED starts blinking and a message appears on the LCD. This message stays on screen until the capacity rises above 20%.

Operating Modes

• Solar charging mode: when solar energy is enough to charge the battery, the controller stays in solar mode. The yellow solar mode LED remains on while it charges through solar power.
• Standby mode: if solar energy is insufficient, the blue hybrid mode LED turns on and a message appears on the LCD. The grid supply then turns on so the battery can charge from the grid.
• Hybrid charging mode: whenever battery capacity drops below 50% or solar energy is insufficient, the controller switches to hybrid mode and turns on the blue LED. It stays in this mode until the battery reaches 100% capacity.

Three-Stage Battery Charging

The Simtek MPPT Plus 120V 70Amp uses a three-stage charging topology. This increases battery life and helps maintain the specific gravity of the battery.

• CC (constant current) mode, stage 1: the green charging LED keeps blinking at an interval of 1 second.
• CV (constant voltage) mode, stage 2: the green LED also blinks at an interval of 1 second.
• Float or trickle charging mode, stage 3: the green LED becomes steady, and then a message appears on the LCD.

Key Features

• Hybrid operation with automatic battery charger cut-off
• 220V output, so you can connect a charger or UPS
• No WAPDA use during daylight
• Automatic switch to WAPDA when evening comes
• Digital display as well as an LED battery level indicator
• 96% efficiency in 12V systems and 97% efficiency in 24V systems
• Wide input voltage range: 30V to 120V
• High rated output current: 70A
• Over-charge and surge protection
• System over-temperature and ambient light detection

Why Choose the Simtek MPPT Plus 120V 70Amp?

This controller suits homes, shops and small offices that run 12V or 24V battery banks with solar panels. Because it can fall back on the grid, it also works well when sunlight varies through the year. In short, it keeps your batteries charged and protected with very little effort.

Installation and Care Tips

First, make sure your panel string voltage stays below the controller’s input limit, even on cold mornings. Then use cables of the right size and keep all connections tight. Also, mount the unit in a shaded, ventilated spot so the fan can keep it cool.
