Sun Energise 15W 12V Solar Charger & Maintainer PRO – MPPT, Waterproof

Efficient 12V charging for your on‑the‑go power needs

Sun Energise delivers a compact, high‑efficiency solar charging solution designed to keep your 12V batteries topped up across cars, boats, RVs, and more. The built‑in MPPT charge controller pursues maximum energy from available sun, with peak conversion efficiency up to 98% and tracking efficiency up to 99%. In practical terms, this means steadier charging during variable light conditions and better use of a sunny day or a shaded garage workspace.

Smart 3‑Stage Charging for safer, steadier power

A three‑stage charging algorithm (Bulk, Absorption, Float) guides the battery toward a safe, stable level while minimizing risk of overcharge. This approach can help maintain battery capacity and readiness between uses, without requiring extra maintenance steps.

• Bulk: rapid accumulation of charge when the battery is deeply discharged
• Absorption: controlled voltage to prevent overheating
• Float: keeps the battery at a ready, maintained level

Robust protections you can rely on

Multiple safeguards protect both charger and battery, including over‑charge/discharge, over‑voltage, over‑current, overload, short circuit, reverse polarity, and over‑temperature. An IP65 waterproof rating adds splash and dust resistance, while spark‑proof design supports safer hook‑up and daily use.

Wide battery compatibility for versatile setups

Designed to work with a broad range of 12V chemistries, it serves as a solar trickle charger and maintainer for gel, Deep Cycle, SLA, Flooded, AGM, Lead‑Acid, and LiFePO4 lithium packs. This flexibility makes it suitable for many vehicles and outdoor systems.

Rugged, efficient build for real‑world use

The module features high‑quality mono solar cells with strong efficiency ratings and a tempered glass face, housed in a corrosion‑resistant ABS frame. The panel and components are built to endure UV exposure, hail, wind, and snow loads, delivering dependable energy capture in diverse environments.

Ease of use at a glance

Setup is simple: connect the three plug‑and‑play cables and monitor charging status via the indicator light. You can quickly verify whether the system is charging and where power is coming from, without complex setup steps.

A practical companion for many off‑grid lifestyles

From daily use in a driveway to extended trips on the water or the road, this solar charger maintains readiness for a wide array of applications, including cars, boats, RVs, campers, lawnmowers, motorcycles, jet skis, tractors, trucks, ATVs, trolling motors, and more.
