Enerdrive ePRO 12V 90A Battery Charger for Off-Grid RVs

Meet the Enerdrive ePRO Battery Charger series, starting with the 12V/90A model that brings industry-leading power conversion into demanding off-grid, marine, and RV systems. Built to perform where others struggle, the ePRO line blends precision engineering with flexible, user-driven charging for multiple battery banks without compromising efficiency or safety.

Why the Enerdrive ePRO stands apart

• Active rectifier output stage and active PFC deliver top-tier efficiency, reducing energy waste and heat while maximizing charge current per AC watt.
• Advanced 4‑stage charging algorithm with temperature compensation optimizes charging for long battery life across a wide range of chemistries, including LiFePO4.
• Fully 3 isolated DC outputs mean you can charge up to three independent battery banks simultaneously, or run them in tandem for higher totals.
• Modular scalability: up to 6 units in parallel, achieving up to 540A total for large solar+generator systems—without sacrificing precision or safety.
• Remote visibility and control via TBSLink for optional remote controls and Dashboard software to author custom charging algorithms tailored to your battery bank.
• LiFePO4 compatibility and a broad battery compatibility profile (Flooded, Gel, AGM, LiFePO4, and Custom) for flexible installations.
• Rugged, purpose-built design for harsh environments with a compact footprint and upright mounting.

Designed for real-world use

Whether you’re powering a boat, an RV, a remote cabin, or an off-grid workshop, the ePRO 12V/90A delivers reliable, fast, and safe charging across three independently controlled channels. The system thrives where fluctuating AC input, varying battery chemistries, and multiple battery banks are the norm, delivering consistent charge currents while protecting your batteries from overcharging and thermal stress.

Use cases that benefit from ePRO’s versatility

• Marine and RV setups with separate starting, house, and auxiliary batteries requiring synchronized charging from a single, intelligent charger.
• Hybrid systems pairing solar, wind, or gensets with backup storage, where parallel operation scales to meet peak demand.
• Off-grid cabins and workshops that demand reliable charging for LiFePO4 or flooded batteries while minimizing energy waste.
• Custom battery configurations in fleets or retrofits where remote management and tailored charging profiles improve longevity and performance.

How it works and why it matters

The ePRO uses a sophisticated power conversion loop that minimizes energy loss and heat, so you get a higher usable charge current from your AC supply. The four-stage charging profile adapts to battery temperature and chemistry, which is crucial for Lithium Iron Phosphate packs as well as traditional flooded batteries. With Dashboard software, you can tailor charging curves to your specific batttery bank—helping you maximize lifespan and performance without guesswork.

Installation, monitoring, and safety

All models feature 3 isolated DC outputs for independent banks, with the option to connect multiple chargers in parallel for higher capacity. The built-in protections guard against common failures: low AC input, short circuits, overheating, overflow charging, and reverse polarity. The rugged IP21 enclosure is designed for upright mounting in exposed spaces while maintaining quiet operation thanks to an efficient cooling system. For remote insight, the standard TBSLink port enables optional remote readout and control, keeping you in tune with your battery health from anywhere the system is accessible.

Tips to get the most from your ePRO

• Match the charger to your battery bank size: 180–900Ah for 12V systems ensures ample headroom for fast, safe charging.
• Enable temperature compensation for LiFePO4 and other chemistries to extend cycle life.
• Use Dashboard to craft a custom charging algorithm if your battery array has unique charge requirements.
• Install in a well-ventilated area and consider the parallel capability if you’re aggregating multiple banks to reach higher totals.

Choose the Enerdrive ePRO Battery Charger to bring precision, efficiency, and flexible control to your 12V or 24V energy systems. With real-world applicability across marine, automotive, and off-grid applications, it’s engineered to deliver reliable charging today and durable performance for years to come.
