Epever DuoRacer MPPT Solar Charge Controller Dual 30A
Upgrade your off-grid setup with the Epever DuoRacer MPPT Solar Charge Controller. This dual battery regulator delivers up to 30A of precise charging power. Advanced MPPT tracking boosts solar efficiency by over twenty percent. You get reliable power for RVs, boats, and campers. Pair sealed or Lithium batteries with automatic start-battery support. Secure, smart, and built for rugged travel.
Key Features
-
Triple MPPT Algorithms Captures peak sun yield without manual tuning.
-
Dual Battery Routing Powers household stores and engine starters from one board.
-
Auto Low-Power Sleep Cuts standby drain when clouds block daylight.
-
MT11 Touch Dashboard Sends live graphs and alerts directly to your handheld meter.
Product Description
You will see fewer cold starts and faster daytime recharges with this upgraded unit. Our engineers fitted high-grade ST and Infineon chips to handle heavy cycling. The wider MPPT window catches weak sunlight earlier and holds it longer. You simply wire your panels, pick your battery chemistry, and let the digital circuit do the math. IP33 sealing laughs off road dust and light spray.
Product Overview
The DuoRacer model manages two separate banks from a single mount. Your main storage feeds lights and appliances. Your auxiliary bank wakes the diesel or gas engine automatically. Parameter menus run through bright LEDs or an optional LCD faceplate. RS485 ports open the door to modular expansions and fleet integrations.
Key Benefits
-
Waste Zero Sunlight Gains twenty to thirty percent more juice than basic PWM setups.
-
Cut Installation Time Two charging paths replace tangled parallel bridges.
-
Protect Your Investment Triple safeguards stop overvoltage, deep discharge, and reversed leads.
-
Free Fridge Power Built-in AES lines spill unused noon watts straight to refrigeration.
Features
Digital three-stage absorption balances cell chemistry and fights sulfation. Temperature-compensated curves adjust charging rates during freezing mornings or desert heatwaves. The standard Modbus layout plugs cleanly into existing SCADA networks. Heavy-duty copper busbars lower resistance and keep voltage drops invisible. You get predictable performance mile after mile.
Specifications
-
Current Options Choose 10A, 20A, or 30A variants for your panel string.
-
Main Batteries Accepts Sealed, Gel, Flooded, LiFePO4, and Li-NiCoMn packs.
-
Start Batteries Auto-recognizes lead-acid cranking voltage on circuit two.
-
Enclosure Grade IP33 resistors shield internals from splashes and grit.
-
Data Ports RS485 serial interface supports meter cables up to ten meters.
What’s Included
Your box contains the primary DuoRacer controller chassis bolt-ready for DIN-rail or flat panel mounting. Pre-stamped terminal guides show exactly where positive and negative wires land. A silicone gasket seals the faceplate against trail vibration.
How to Use
Screw your solar inputs into the marked PV terminals first. Join your main storage bank second, then hook the starter bank third. Flip the menu switch to match your LiFePO4 or flooded chemistry. Press the AES toggle to redirect surplus watts to your onboard cooler. Scan the display daily and adjust load thresholds if needed.
Customer Benefits
You trade endless multimeter checks for crystal-clear dashboard readouts. Real-time percentages tell you exactly how much energy today captured. Stable charging curves extend battery service life by years. Automated cutoffs remove worry from overnight trips on remote trails.
Ideal Uses
Drop this controller into camper dashboards, marine breaker boxes, or mobile workshop frames. Run it alongside backup inverters or hybrid grid ties. Deploy it for pop-up festivals, hunting camps, and coastal cabins. Pair it with lightweight folding panels for rapid site swaps.
Who It’s For
DIY builders upgrading tired PWM gear will love the instant jump in yield. Van lifers who separate kitchen fridges from engine startups will save space. Fleet managers juggling multiple auxiliary batteries will appreciate the telemetry port. Anyone tired of guessing charge states belongs behind this display.
5 Frequently Asked Questions
-
Do I need extra firmware to scan battery temps? No, the internal chip handles compensation automatically without software updates.
-
Can I daisy chain two controllers together? Yes, link identical units across the shared RS485 line to expand capacity safely.
-
Will the stand-by mode reset my clock settings? The memory retains your program steps through complete power blackouts.
-
Does the AES outlet override my fuse box? It bypasses your main panel to feed cold compressors directly from solar surplus.
-
Are mounting holes drilled pre-cut? Factory pilot marks align with standard commercial din-rail brackets and flat surfaces.
