Solar controller Review: Great Value for the Price - You go walking into your local HF store and you will find the Thunderbolt Magnum charge controller going for $79.00. To be honest $79.00 is a little steep for a basic controller with a LCD. The info that the LCD provides is pretty basic. Giving you the volt status of your batteries and amps coming in or going out depending if your using the load terminals on the controller. The good news is that on desertcart you can find real good deals on this exact same controller. I bought 2 within a week. The first one I purchased was $42.00 including shipping. The second one was $29.99 including free shipping. Prices do seem to fluctuate on desertcart a lot depending on the vendor. The bottom line is that I bought 2 for the price of 1 at HF. Now for the price I paid, this is a very good controller. Controllers in the $30.00 to $40.00 price range give you LED status, charging, charged, etc. If you want digital info it requires using a multimeter. This will do everything that a basic controller will do and provide you with good basic info on the LCD. For $30.00 this controller is a steal and for $40.00 a very good buy..... Review: Operating procedures not a match with the manual - When reading the manual and it describes the use of the display button reality is different. As you press the display button to cycle through the different modes it doesn’t match with what the manual describes should be happening. For the price this controller should have at least a display that shows what it’s doing as the default screen. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B009JCTULK | | Best Sellers Rank | #264,921 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #1,052 in Solar Panels | | Customer Reviews | 3.2 3.2 out of 5 stars (63) | | Is Discontinued By Manufacturer | No | | Item Weight | 13.6 ounces | | Item model number | 68738 | | Product Dimensions | 6.9 x 4.1 x 2 inches | ## Images ![500 Watt Solar Charge Controller - Image 1](https://m.media-amazon.com/images/I/51Z0ZqVe8TL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Value for the Price *by C***S on May 25, 2013* You go walking into your local HF store and you will find the Thunderbolt Magnum charge controller going for $79.00.

As you press the display button to cycle through the different modes it doesn’t match with what the manual describes should be happening. For the price this controller should have at least a display that shows what it’s doing as the default screen. ### ⭐⭐ No cord included - no longer has an 8mm connection port. *by D***D on November 9, 2025* So disappointed. I used to have this controller (which stopped working after getting wet) and it had ab 8mm connection hole. That is not there anymore and the cord in the picture is not included (!!), so I'm stuck either trying to find that cord and paying more or trying another product. I've contacted Thunderbolt, but no word yet... (Pictured is the old version and the new one with fewer connection options and no cord.) ## Frequently Bought Together - 500 Watt Solar Charge Controller - BougeRV Solar Connectors Y Branch Parallel Adapter Cable Wire Plug Tool Kit for Solar Panel - Renogy 30A 12V/24V PWM Solar Charge Controller with LCD Display Flush Mount Design Negative Ground, Compatible with Sealed, Gel, Flooded and Lithium Batteries, Adventurer 30A,black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/6767214-500-watt-solar-charge-controller](https://www.desertcart.in/products/6767214-500-watt-solar-charge-controller) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-05*
