Compact MPPT Solar Charge Controller — 25A & 50A | Small, Efficient MPPT for Home & Small Solar Systems

India’s advanced compact MPPT solar charge controller — available in 25A and 50A models for 12V, 24V, 36V, and 48V battery banks. Supports Lithium-ion, LiFePO4, Lead Acid, and Ni-Cd batteries (factory pre-set). Wall-mount design. 98.8% conversion efficiency. Built for residential, small commercial, and inverter battery charging applications.

The Right MPPT Solar Charge Controller for Small & Medium Solar Systems

Not every solar installation needs a large industrial controller. If you are building a home rooftop solar system, adding solar charging to your existing inverter and battery setup, or setting up a small off-grid power system — what you need is a compact, reliable, and affordable MPPT solar charge controller that delivers maximum efficiency without unnecessary bulk or cost.

The Systellar CC-MPPT-Compact is purpose-designed for exactly this need. It packs the same advanced Synchronous Buck Converter MPPT technology found in high-end industrial controllers into a slim, wall-mountable unit that fits neatly in any home, office, or small installation. At 98.8% conversion efficiency, it extracts every possible watt from your solar panels — delivering up to 25% more charging energy than a PWM controller of the same rating.

Who Should Choose the CC-MPPT-Compact?

This controller is the ideal choice if you match any of these profiles:

• You have a home inverter and battery setup (12V ,24V, 36V, 48V) and want to add solar charging to reduce electricity bills
• You are building a small off-grid solar system with 200W to 3240W of solar panels
• You need a 25A or 50A MPPT charge controller for a residential rooftop solar installation
• You want automatic battery voltage detection — the controller detects your battery bank voltage and configures itself
• You are upgrading from an old PWM solar charge controller and want significantly better charging performance
• You need a wall-mountable solar controller that takes up minimal space
• You are charging LiFePO4 or lithium batteries and need a controller with the correct charging profile

If your system is larger — requiring 75A charging current, RS485 remote monitoring, or a built-in PowerSaver relay — please see our CC-MPPT-Gen6, which is built for those higher-demand applications.
