DC Solar is rather infamous in the renewable energy world, but they produced thousands of solar trailers before being shut down in 2018. They pop up quite often on auction sites, and can often be had for quite a good price. With up to 2350 watts of PV power and 12kW of power, and often including a diesel generator, there's no doubt that a DC Solar trailer is often a cheap way to own a pre-built solar system.

DC Solar trailers typically feature one or two SMA Sunny Island inverters, a Midnite Classic 250 charge controller, and up to 10 235-watt solar panels. Some even have a backup diesel generator.

Renewed Power

The downside is that these trailers may weigh up to 10,000 lb, of which 4,000 lb is in the old lead acid batteries alone. And since many of these have been sitting for nearly a decade, the batteries are nearly always dead and gone.

Higher Wire has developed a drop-in lithium battery to replace the existing lead acid system. Weighing only 750 lb for 24 kWh of power, the batteries can be swapped in as little as a few hours, using the existing Anderson connectors and requiring only one additional connection for the communication cable to the inverters.

We use quality lithium iron phosphate (LiFePO4) that have undergone our strict testing and renewal process. This means that we can keep costs down while maximizing the lifespan of the cells we use, while offering a warranty and support for up to 5 years.

Our advanced battery management system (BMS) has wifi output for remote monitoring/troubleshooting and the ability to connect to your existing network. It also send key information such as state of charge (SOC) to the inverters, and will prevent system damage from over- or under-voltage at the pack and even cell level.

Double or Triple the Capacity!

There's enough space in a typical DC Solar trailer to triple the capacity, and our advanced BMS is able to connect in parallel in a master-slave configuration to monitor the health of each battery.


We can install the battery at our facility, which includes lead-acid battery recycling, for an additional fee. Contact us to arrange installation.


Lithium batteries can be potentially dangerous! Even when properly handled, lithium batteries may ignite or explode. It is imperative that you use quality battery management and charging systems when operating lithium batteries. All users of lithium-ion batteries MUST read the warning and safety instructions on our website before using lithium-ion batteries.


All of these packs have greater than 80% of original capacity and come with a limited 5-year warranty. If a cell or pack fails within that window, we will replace it no questions asked. Note that the replacement may not have the same capacity as the original purchase, and may be lower capacity. See our warranty page for limitations.

We ship the majority of our orders by the next business day. Lithium batteries may take up to two business days to process to accommodate inspection and logging into our system.

Our shipping rates are based on the weight of all ordered products plus estimated weight of packaging. We make every effort to forecast an accurate shipping cost, but cannot be 100% certain in all cases. Please contact us at sales@higherwireenergy.com with any questions prior to purchase.

We pack and label all lithium battery shipments in accordance with Federal Regulation 49CFR173.185, as well as USPS Publication 52 Hazard Class 9 or UPS/Fedex guidelines. Unless otherwise stated, lithium batteries are not eligible for free shipping.

We try to pack all items in an order in a single box, however we may on occasion need to ship items separately. Special shipping does not apply to lithium ion batteries, and orders that include batteries may not qualify for free or expedited shipping.
