Technical Specs

Professional grade solar charge controller to connect solar panels to batteries. Includes an easy to use bluetooth phone app.

Description

Recommended for charging batteries with solar energy. When using solar on your boat, yacht, van or RV you will need a charging device which converts the energy which your panels are producing to a stable charging voltage and current that your batteries can easily accept. A solar controller will increase the efficiency of your panels, increasing the amount of energy available for your use. The Smart Solar series from Victron also includes Bluetooth smart monitoring, or with the GX series of monitoring equipment, a user can set charging parameter and battery type (choose the lithium setting for DL battereies), and monitor and record solar yields. We’re a fan of this charge controller because of it’s professional grade performance and the easy to use bluetooth phone app. Datasheet available here. A solar charge controller is recommended for any solar energy system with 100 watts of solar panels or more.

Technical Specifications

  • What is a solar charge controller?: A charging device which converts the energy which your panels are producing to a stable charging voltage and current that your batteries can accept easily.
  • Nominal Power & Peak Efficiency: 220 watts, 98% efficiency
  • Rated charge current: 15 amps
  • Optimized for Solar Energy: Compatible with any solar panel. For higher efficiency we recommend using with a battery and a solar charge controller.
  • How does this fit into my off-grid, home power system?: This controls the charging of your batteries with solar panels and greatly increases performance. To use the energy you will an inverter. Inverters make it easy to use energy available from your batteries in the form of an AC wall plug.
  • MPPT: Ultra Fast Maximum Power Point Tracking: By constantly monitoring the voltage and current output of your solar (PV) panels, MPPT technology ensures that every drop of available power is rinsed out of your panels, and harvested for storage. The advantage of this is most noticeable when the sky is partially clouded, and light intensity is constantly changing.
  • Intelligent Load Output: The intelligent Load output function prevents damage caused by running batteries 'flat'. You can configure the voltage at which SmartSolar disconnects a load - thereby preventing excessive drain on your batteries. And here's the clever bit: SmartSolar will attempt a 100% recharge every day. If it can't - during periods of poor weather - it raises the disconnect voltage, daily, until it achieves success. We call this feature BatteryLife because it maintains the health, and extends the life of your battery.
  • Remote Monitoring and Control: Remotely control and monitor the extensive features of your SmartSolar MPPT charger with built-in Bluetooth by pairing it with your smartphone or other device via VictronConnect. If your installation is connected to the internet Victron Remote Management Portal (VRM) provides access to the full power of your MPPT, anytime, anywhere; both services are free to use. For remote installations - even when there is no internet connection or phone signal nearby - you may be able to monitor your MPPT by Bluetooth-pairing with a LoRaWAN (long-range wide area network) device, available optionally.

FAQ
  • Twice the Power?

    Yes! Here at Dakota Lithium we build all of our batteries with lithium iron phosphate technology which has many distinct advantages over traditional batteries. Including 60% less weight, a charging speed that is up to 5X faster, and a significantly longer lifespan (5-10 years longer on average). One of the most noticeable advantages however is the flat voltage curve. Unlike a lead acid battery where the voltage drops as you use the battery a Dakota Lithium battery has a steady voltage for 99% of the battery’s charge. That means you get all the power down to the last drop and double the usable power of traditional batteries.

  • Are Lithium Batteries Safe?

    Dakota Lithium batteries are 100% safe & reliable. Our signature chemistry, Lithium Iron Phosphate (LiFePO4), does not contain rare earth elements (like Cobalt) or heavy metals, is non-toxic, including no lead or acid, is non-corrosive, does not off gas, requires no watering or maintenance, can be placed in any orientation, and unlike other lithium batteries will not explode or catch fire. In addition, each Dakota Lithium battery is protected from over heating, over charging, and short circuiting, by a battery management system (BMS) microchip that also extends the lifespan and is contained in a rugged, waterproof case (although enough water can conduct electricity between the terminals, so don’t submerse the battery). For best performance & reliability we recommend using a LiFePO4 charger.    

  • How do I charge a lithium battery?

    Dakota Lithium LiFePO4 batteries perform best when charged by a LiFePO4-compatible battery charger. LiFePO4 batteries require a different charging profile and voltage requirements compared to traditional battery chargers. Chargers designed for different chemistries may work, but they may not charge a Dakota Lithium battery to full capacity. It’s important to select a charger that has a LiFePO4-compatible constant-current constant-voltage (CC/CV) charging profile, provides the correct charging voltage for your battery, does not exceed the charge current (amp) for the battery, and has a charge indicator LED to let you know when the battery is fully charged. You can find more information on How to Charge Dakota Lithium and LiFePO4 batteries on our website. If you need help finding a compatible charger for your Dakota Lithium battery, or if you want to check your current charger compatibility, please reach out to our support team.

  • Will cold weather affect my battery?

    Your Dakota Lithium battery will discharge normally between a range of -20F and 120F (-29C to 49C). DL batteries are commonly used among ice fishers for their flashers and ice augers, so they are quite resilient and are frequently used in cold climates. In cases of extreme cold however, it is recommended that the batteries be insulated. We also do not recommend charging our batteries below freezing temperatures. If you are planning to regularly charge your battery below freezing temperatures we recommend the DL+ 12V 135Ah battery which has an internal heating element and is optimal for use in cars, trucks, RVs, off grid solar, and any application where the battery will be charged regularly in extremely cold environments (like a North Dakota winter).

  • What battery do I need for my RV or Camper Van?

    The industry standard house battery size used in most RVs, Campers, and #VanLife builds is the DL 100Ah battery. This is a drop in replacement for AGM and most lead acid batteries. If you are charging off your engine’s alternator we recommend a Victron DC-DC smart charger. If charging off solar panels we recommend a Victron Smart Solar charge controller, or if you have a solar charge controller choose the lithium setting. A handy size chart for number of batteries needed by size of RV is available here.

Works good. I like the Bluetooth application.

Steve Harsh

I’d rather have a window on the controller to read without having to use my phone to monitor the settings. The app doesn’t recognize my particular model ?

Travis Olson

Works great

Christopher Krasovic

Your batteries are great I still have to hook up the solar control box that I've bought from you I'm using a 200 watt solar panel to it and then to the battery to run my TV I'll let you know how it goes when I'm done but your batteries are everything you say they are
