Solar MPPT Charge Controller — Reliable, efficient battery charging
Overview
This compact MPPT solar charge controller optimizes solar harvest and protects your battery system. It uses an advanced MPPT algorithm with multiple-peak detection, supports common 12V/24V systems, and includes clear status indicators and safety protections for reliable, low-maintenance operation.
Benefits
- Get more usable energy from the same solar array so your battery stays charged longer.
- Protect your battery and electronics automatically — less worry about overcharge, short circuits, or reverse wiring.
- Install quickly and with fewer configuration steps because the controller detects 12V or 24V systems automatically.
- See system status at a glance with a simple LED bar and an informative display, or add a remote meter for convenient monitoring.
- Work in a variety of environments thanks to splash protection, conformal-coated electronics, and wide operating temperatures.
- Use with many battery chemistries — several presets plus custom settings reduce guesswork and improve battery life.
Features
- Advanced MPPT algorithm for maximum power extraction from PV panels.
- Multiple-peak detection technology to find the true maximum power point in complex arrays.
- MPPT tracking efficiency above 99.5% and up to 98% conversion efficiency.
- Supports common negative grounding for simplified wiring.
- Preset support for up to 9 battery types plus custom battery configuration.
- Automatic detection of 12V or 24V DC system voltages.
- Concise LED bar for quick solar and battery status; large display for detailed parameters and fault codes.
- Optional plug-in remote digital display meter and external battery temperature sensor.
- Comprehensive safety protections: overcharge, undercharge, short circuit, reverse polarity, and thermal protection.
- Durable construction: splash-proof IP43 rating, rubber terminal cover, and conformal coating on internal boards.
- Designed to international safety and EMI standards (UL1741, EN/IEC 62109-1, EN61000-6-1/6-3, FCC 47 CFR Part 15 Subpart B).
