150A MPPT Solar Charge Controller, 12V/24V/36V/48V Auto with LCD Display, Smart Timer & Dual USB for RV, Boat, Cabin, Off-Grid Power System
In Stock
Listed at 150 A, the highest rating in the category, this controller auto-detects 12 to 48V systems and has a backlit LCD, timer modes and two USB ports. The maker describes it as a hybrid MPPT/PWM design where PV voltage follows battery voltage during bulk charging, suiting budget experiments rather than a primary van system. A 150 A rating at 7 oz (190 g) is unlikely, since 100–120 A MPPT units listed weigh 6.6–8.7 lbs (3–4 kg).

Features
- 【MPPT Solar Charge Controller 150A – All-in-One Power Command Center】Stop juggling multiple controllers. This universal brain automatically recognizes 12V, 24V, 36V, and 48V systems and works with any battery (Lead-Acid/Lithium). Whether it’s your weekend RV trip, sailboat, remote cabin, or whole-home backup, it’s the single solution for true energy independence.
- 【Hybrid MPPT PWM Solar Regulator – Honest Technology & Outstanding Price-Performance Ratio】We believe in transparency. This controller employs an intelligent hybrid charging approach (MPPT+PWM) that ideally combines efficiency and value. It delivers excellent charging performance at an affordable price, making advanced solar management a smart investment for home, RV, camping, and more.
- 【Auto Recognition Solar Panel Controller – Intelligent MPPT Algorithm】The 150A MPPT solar controller adopts advanced MPPT maximum power point tracking technology algorithm, significantly improving the energy utilization efficiency of the solar system, and automatically recognizes 12V/24V/36V/48V; Dual USB 5V charging ports can quickly track the maximum power point of the PV array in any environment, with a tracking efficiency of no less than 99.5%. And significantly improve the energy utilization efficiency in solar energy systems.
- 【LCD Solar Charge Controller Display – Upgraded Vision】See Your Solar Harvest in Real-Time. Our SA Series Upgrade puts you in total control. The clear LCD now visually displays your solar panel’s voltage and input power. No more guessing — know exactly how much free energy you’re making, maximizing your return on investment with every sunny day.
- 【Safe use – Solar Controller with Overvoltage Protection】The LCD backlit screen displays real-time data: battery voltage, PV charging/discharging current, temperature, and error codes. Three layer protection can be used to immediately cut off power during surges (exceeding 32V), short circuits, or overheating, and can be used for communication base stations, home power supply systems, traffic lights, solar street lights, courtyard lighting systems, etc. Very suitable for off grid homes, solar street lights, and remote installations.
- 【Technical Note】This controller features adaptive smart charging logic. It utilizes an MPPT-based algorithm to optimize solar harvesting while employing high-frequency switching regulation to manage power delivery. During bulk charging, PV input voltage dynamically follows battery voltage. Unlike traditional DC-DC buck-converter MPPTs, this unit integrates optimization software with PWM-style hardware execution—balancing efficiency with robust high-current performance.
