It has been over 6 months that she has not had power. I put together a system that I could order from desertcart and send most of the components to Puerto Rico directly. I ordered the SolarEpic 40A MPPT Solar Charge Controller, four Uni-Solar PVL-136 PowerBond PVL 136 Watt Flexible Solar Panels, a POTEK 2000W Power Inverter Three AC Outlets 12V DC to 110V AC and the miscellaneous cables and fuses. I prewired the controller and the inverter and wrote a detailed set of instructions on how to connect everything else. Luckily, I found in PR the batteries at Batteries Plus, and I ended up using two 12 vdc 155 Amp-hours for the project. My sister and my nephew installed the system 03/03/2018 and it has been powering her fridge, a few LED lights, a fan and charging phones and computers since with no problems. These products are outstanding and provide very impressive performance. Review: plug and play, works great. - I bought one of these for a solar setup in my cab over camper. It was basically plug and play with a lead acid battery and I've had zero issues with it this fall. When I first hooked it up, I had the polarity wrong from the solar panels. The unit didn't give a useful error message or anything, just showed no solar power, but mainly it protected itself and I was able to root-cause the problem. It has a nice timer feature that lets you auto-run a fan or whatever on a schedule if you want to move air through your camper each day. ## Features - Negative Grounding Design and advanced MPPT control algorithm make it charging efficiency no less than 99.5%, it maximize the charging power as a way of saving the energy. - 100V Max PV Input allow you connect 4 x12V solar panel connecting in series, it minimize the charging current on solar panel 's leads to save power loss. - Compatible with LiFePO4 & Li(NiCoMn)O2 Batteries, with built in preset lithium battery type, it's not require setting charging parameters for lithium batteries. - Work with both 12v battery system and 24v battery system, It allows 24V Solar Panels (or Even Higher Voltage) Charging 12v/24v Battery - Standard Modbus communication protocol with RS485 interface , it can be monitored by cellphone APP(eBox required) , PC Software and MT52 remote meter ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07K9HBYPY | | Best Sellers Rank | #390,944 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #443 in Renewable Energy Controllers | | Customer Reviews | 4.5 4.5 out of 5 stars (276) | | Is Discontinued By Manufacturer | No | | Item Weight | 5.37 pounds | | Item model number | 4210AN50RTS | | Manufacturer | Epsolar | | Operating Temperature | 55 Degrees Celsius | | Product Dimensions | 9.92 x 7.09 x 2.48 inches | ## Product Details - **Brand:** SolarEpic - **Color:** grey/white, Black heat sink - **Display Type:** LED - **Item Weight:** 2.44 Kilograms - **Material:** Plastic with Metal (Heat Sink) ## Images ![4210AN with MT50 Meter - Image 1](https://m.media-amazon.com/images/I/61pZFuIPtjL.jpg) ![4210AN with MT50 Meter - Image 2](https://m.media-amazon.com/images/I/713ojeOkp4L.jpg) ![4210AN with MT50 Meter - Image 3](https://m.media-amazon.com/images/I/81vyeWGaKLL.jpg) ![4210AN with MT50 Meter - Image 4](https://m.media-amazon.com/images/I/51bjq2408ZL.jpg) ![4210AN with MT50 Meter - Image 5](https://m.media-amazon.com/images/I/614tlcinw5L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable Solar Power System *by I***N on March 27, 2018* I wanted to help my sister after Hurricane Maria.

It was basically plug and play with a lead acid battery and I've had zero issues with it this fall. When I first hooked it up, I had the polarity wrong from the solar panels. The unit didn't give a useful error message or anything, just showed no solar power, but mainly it protected itself and I was able to root-cause the problem. It has a nice timer feature that lets you auto-run a fan or whatever on a schedule if you want to move air through your camper each day. ### ⭐⭐⭐⭐⭐ Excellent Quality for the price! *by A***R on October 19, 2018* This MPPT Charge controller seems to be working quite well. I am running 250 watts of solar panels through it to two 100ah Deep-Cycle AGM batteries. This is day 3 and even on cloudy days (here in NW Washington State), my batteries have never dipped below 12.6. And I watch 24 inch smart tv with 50 watt speakers, a small led light, and a small fan. I keep a fan on all night to help me sleep. I am really glad I bought this charge controller and and happy to give it a 5 star rating. ## Frequently Bought Together - EPEVER 40A MPPT Solar Charge Controller 100V PV Max Input Negative Ground LiFePo4 Battery Charger W/ MT50 Remote Meter & Temperature Sensor Tracer4210AN - CHTAIXI DC Miniature Circuit Breaker, 2 Pole 1000V 63 Amp Isolator for Solar PV System, Thermal Magnetic Trip, DIN Rail Mount, Chtaixi DC Disconnect Switch C63 - 10pcs 1 AWG-3/8 Battery Lugs,Copper Wire Lugs,UL Listed Heavy Duty Battery Cable Ends,Tubular Ring Terminals,AWG Crimp Wire Ring Lugs,Battery Terminal Connectors with 3:1 Heat Shrink Tubing --- ## 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.co.uk/products/98380066-4210an-with-mt50-meter](https://www.desertcart.co.uk/products/98380066-4210an-with-mt50-meter) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-19*
