The battery cable should be as short as possible to minimize loss. The charge regulator is only suitable for regulating solar modules . never connect another charging source to the charge regulator. Battery type description： B1: Lead-acid(OPEN, AGM, GEL), B2: Ternary Lithium batteries , B3: Lithium LiFePO4 . Feature Built-in industrial micro controller Large-screen Lcd display, charging and discharing current display, cumulative power generation and discharge power query, temperature display, light control + delay control; adjustable charge and discharge parameters, with power-off memory and other functions Dual USB output , thr max current of 2.5A , to support mobile phone charging Build-in short-circuit protection, open-circuit protection, reverse protection, over-load protection Reverse current protection, low heat prodution Connect the battery to the charge regulator-plus and minus Connect the load to the charge regulator-plus and minus Connect the photovoltaic module to the regulator-plus and minus The reverse order applies when deinstalling, an improper sequence order can damage the controller! Operation instructions short press menu key to cycle through the interface and parameters; long press the menu button for 3S to enter the settings manually, this number will be flashing, into the corresponding set project on turn, turn key adjustment parameters you want value, after the completion of the system of automatic memory setting value and exut setup menu; Function declaration discharge recovery voltage: refers to the battery discharge protection, the battery voltage to restore voltage, open the output; the diacharge cut-off voltage: refers to the battery diacharge to the voltage when the load off, to protect the battery, to prevent the battery over daicharge damage. Load operstion mode [24H]Load output 24hours(except for battery under voltage) [1-15H]Load on after sunset and closed after setting hours [0H]Dusk to dawm Review: Solar Charge Controller Works Great - This 100a version works great and you must do your research before buying any of these items to prevent premature failure and possible fires. I consult for remote solar powered systems on a budget. One thing to note is writing down how many amps you need from this controller as it will output 12V or 24V depending on your setup. I recommend 24VDC battery setups on this, 24VDC inverters, and it will then need solar panels that supply 24V+ to this controller. Its good to read all the instruction booklets for parts to see what its hookup requirements are and its min/max settings needed. Review: good - good ## Features - Advanced Maximum Power Point Tracking (MPPT) technology, with efficiency no less than 99.5%. High quality components, perfecting system performance, with maximum conversion efficiency of 98%. Ultra-fast tracking speed and guaranteed tracking efficiency. - Large-screen LCD display, charging and discharging current display, cumulative power generation and discharge power query, temperature display, light control + delay control; adjustable charge and discharge parameter, with power-off memory and other functions. - Dual USB output, the maxmum current of 2.5A, to support Apple's mobile phone charging. For a 12V battery, the maximum solar panel input voltage is 23V; for a 24V battery, the maximum solar panel input voltage is 46V. - All necessary protections equipped, adjustable controlling parameter of the system, easy to set up and operate. - Build-in short-circuit protection, open-circuit protection, reverse protection, over-load protection. reverse current protection, low heat production, having self-recovering and do not damage the controller. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08GBVNP67 | | Best Sellers Rank | #125,671 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #100 in Renewable Energy Controllers | | Brand | iSunergy | | Brand Name | iSunergy | | Color | 40A | | Customer Reviews | 3.8 out of 5 stars 295 Reviews | | Display Type | LCD | | Item Weight | 0.3 Kilograms | | Manufacturer | iSunergy | | Material | Lead | | Material Type | Lead | | Model | YCX40A | | Part Number | YCX40A | | UPC | 732376584678 | | Unit Count | 1.0 Count | | Voltage | 24 Volts | ## Product Details - **Color:** 40A - **Brand:** iSunergy - **Voltage:** 24 Volts - **Material:** Lead - **Item Weight:** 0.3 Kilograms ## Images ![MPPT Solar Charge Controller 40A 12V/24V Auto Solar Panel Intelligent Regulator with Dual USB Port LCD Display for Lead Acid Batteries - Image 1](https://m.media-amazon.com/images/I/71Lb7O9te6L.jpg) ![MPPT Solar Charge Controller 40A 12V/24V Auto Solar Panel Intelligent Regulator with Dual USB Port LCD Display for Lead Acid Batteries - Image 2](https://m.media-amazon.com/images/I/71JBjecw4yL.jpg) ![MPPT Solar Charge Controller 40A 12V/24V Auto Solar Panel Intelligent Regulator with Dual USB Port LCD Display for Lead Acid Batteries - Image 3](https://m.media-amazon.com/images/I/71UnfUdU9OL.jpg) ![MPPT Solar Charge Controller 40A 12V/24V Auto Solar Panel Intelligent Regulator with Dual USB Port LCD Display for Lead Acid Batteries - Image 4](https://m.media-amazon.com/images/I/61xOUZKimnL.jpg) ![MPPT Solar Charge Controller 40A 12V/24V Auto Solar Panel Intelligent Regulator with Dual USB Port LCD Display for Lead Acid Batteries - Image 5](https://m.media-amazon.com/images/I/71pUiMmsXOL.jpg) ## Available Options This product comes in different **Amperage** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Solar Charge Controller Works Great *by A***S on November 25, 2024* This 100a version works great and you must do your research before buying any of these items to prevent premature failure and possible fires. I consult for remote solar powered systems on a budget. One thing to note is writing down how many amps you need from this controller as it will output 12V or 24V depending on your setup.

Its good to read all the instruction booklets for parts to see what its hookup requirements are and its min/max settings needed. ### ⭐⭐⭐⭐⭐ good *by A***R on March 23, 2026* good ### ⭐ Menu won't open, No Voltage regulation during charging. Voltage too high. *by K***N on January 12, 2026* I set it up exactly as instructions directed. There was no control of the charging Voltage with the 60A charge controller. It appeared to "pass through" Solar Panel Voltage directly to the battery. Holding down the Menu button 3S did not open manual settings. There was no way to select the battery type. There were 15V being applied to the AGM battery. The unit emitted a smell of hot electronics. This could have killed my battery and or caused a fire. ## Frequently Bought Together - iSunergy MPPT Solar Charge Controller 40A 12V/24V Auto Solar Panel Intelligent Regulator with Dual USB Port LCD Display for Lead acid Batteries - 220W Solar Panel, 25.4% High Efficiency Monocrystalline with 10BB Hidden Busbar,MC4 Connectors, IP68 Waterproof for 12V/24V Off-Grid, RV, Boat, Cabin, Camping, Lightweight Outdoor Solar Power --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/261648684-mppt-solar-charge-controller-40a-12v-24v-auto-solar-panel](https://www.desertcart.in/products/261648684-mppt-solar-charge-controller-40a-12v-24v-auto-solar-panel) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-24*
