Bateria Power 10A 12V MPPT Solar Charge Controller, Intelligent Solar Panel Regulator with LED and LCD Display, Compatible with Sealed Flooded Gel AGM Lithium LiFePO4 Battery

Very pleased with this. Most regulator have horrible fiddly screw connectors but this is all plug and play so very easy to install. Works very well and the LCD display is excellent especially as you can switch the illumination on so you can check what is going on.

If your RV is “Solar Ready” or pre wired for solar that typically means you have a small SAE connector you can plug a solar panel into. The problem is you must cannot plug any solar panel directly into the plug. You need a charge controller that takes power from a 24v solar panel and converts it to a voltage that is suiyfor your 12V RV batteries. This unit is an MPPT (maximum PowerPoint tracking) charge controller that is perfectly suited for the task. It’s also a great way to solarize other 12v systems around the homestead such as automatic gates, keeping your generator starter battery charged, keeping mower and ATV battery charged and landscape lights.

Reliable product, it is the second one purchased. The first charger is already operating for more than 2 years with LFP battery. Highly recommended.

I was disappointed that the MPPT (Maximum Power Point Tracking) function on these Bateria regulators does not include the ability to charge when panel voltage is below battery voltage. A regulator I purchased 7 years ago had MPPT that could charge even with panel voltage below battery voltage, so I replaced the simpler "PWM regulator" that came with the 175W solar panel I installed on my boat. This MPPT unit was 4x the price of the Bateria units, but is still working like a charm. The ability to charge with panel voltage below battery voltage makes a noticeable increase in the average energy delivered by a solar panel - especially in chronically poor sunlight situations. When sunlight conditions are poor (meaning EVERY morning and late afternoon when the sun gets low, and ALL DAY on cloudy days) the panel output voltage is lower than battery voltage, and simple PWM regulators (and even MPPT regulators such as this Bateria) are unable to provide ANY charging. (In fact, all regulators slowly discharge the battery under those conditions.) When needing to keep batteries of seldom-used vehicles charged in Northern latitude Winters, enough sunlight to charge may not occur for weeks at a time - and even then at most for 6 hours/day. I purchased 4 Bateria 10A units and tested them in my electronics lab. All 4 responded when voltage was applied, but none would charge unless input (panel) voltage was above output (battery) voltage. I then purchased 4 more of the MPPT units installed on my boat and put them in the same test setup. Output to charge the 12 battery was produced even with input (panel) voltage as low as 5 volts. I plan to use one of these MPPT units to help maintain a Recreational Vehicle (RV) battery during the Winter when short drives are not sufficient to restore a healthy battery charge. All will be used - one per panel - on higher-power panels (all slightly different) during my travels so that each panel will simultaneously produce its maximum power into a common battery regardless of differences in shading (common in campgrounds) or sun angle.

Sehr praktisch beim Camping kann man sehr gut gebrauchen

Tut was es soll. Keine Probleme bisher
