Battery Maximizer Kit – 18W Solar Panel + 10A Panel Mount Charger
Keep your dump trailer battery charged and ready with the Primary Mover Battery Maximizer Kit. This kit combines an 18-watt solar panel with a 10-amp panel mount charger to help maintain your 12V battery system whether your trailer is parked at home, stored between jobs, or sitting away from shore power.
Dead batteries are one of the most common issues on dump trailers, truck beds, and 12V hydraulic power units. Parasitic draw from remotes, solenoids, control modules, and other electronics slowly drains battery voltage over time. This kit is designed to help offset that battery loss and reduce the chances of coming back to a weak or dead battery.
When you have access to shore power, the 10-amp AC panel mount charger gives you a dependable way to recharge your battery. When shore power is not available, the 18W solar panel helps offset parasitic load and can slowly maintain or recharge the battery over time under the right conditions.
What’s Included
- 18-Watt Solar Panel
- 10-Amp Panel Mount Charger
- Designed for 12V battery systems commonly used on dump trailers and hydraulic equipment
Why This Kit Is Beneficial
- Shore Power Charging: Conveniently charge your battery when your trailer is parked at home, at the shop, or not in use.
- Solar Battery Maintenance: Helps offset parasitic draw when your trailer sits away from AC power.
- Helps Reduce Dead Batteries: Maintains battery readiness between jobs and during storage.
- Supports Battery Health: Reduces the risk of deep discharge that can shorten battery life.
- Ideal for Dump Trailers: A practical solution for dump trailer batteries, hydraulic power units, and trailer-mounted 12V systems.
Key Features
- 18W Solar Output – Better suited for real-world trailer applications than undersized maintenance panels
- 10A AC Charger – Reliable shore power charging for faster battery recovery
- 12V Battery Compatible – Designed for dump trailers, truck beds, and hydraulic systems
- Helps Offset Parasitic Load – Supports battery maintenance during idle periods
- Trailer-Ready Setup – Ideal for work trailers and harsh-use environments
Recommended Applications
- Dump trailers with 12V hydraulic power units
- Truck dump bed conversions
- Equipment trailers with battery-powered accessories
- Trailers that sit for extended periods between uses
- Customers looking to reduce battery drain during storage
Important Performance Expectations
The AC charger is the primary solution for fully recharging your battery when parked near power. The solar panel is there to help offset parasitic draw and provide slow maintenance charging over time. Solar charging is beneficial, but it is not intended to replace a high-output charger for rapid battery recovery.
Even a small amount of solar support can make a big difference over time. It is always ideal to have something helping offset parasitic load, even during shorter storage periods.

Frequently Asked Questions
Click to expand
Why do I need this kit?
This kit helps prevent one of the most common problems on dump trailers and hydraulic systems: dead batteries caused by parasitic draw.
The 10-amp panel mount charger gives you shore power charging when the trailer is parked at home or at the shop, while the 18-watt solar panel helps offset parasitic load when shore power is not available.
Will the solar panel charge my battery?
Yes, but with realistic expectations.
The solar panel is best used to offset parasitic draw and provide slow maintenance charging over time. It can help support battery health and reduce discharge, but it is not intended to recharge a heavily drained battery as quickly as shore power.
What is parasitic draw?
Parasitic draw is the small amount of battery power used by electronics even when your trailer is not actively operating. This can include remotes, control modules, wireless systems, and other electrical components.
Over time, parasitic draw can leave you with a weak or dead battery if nothing is replacing that lost energy.
Why is shore power charging important?
Shore power charging gives you a reliable way to recharge your battery when your equipment is parked and not in use. This is especially helpful at home, at the shop, or during longer storage periods.
The included 10-amp charger is the best option for restoring battery charge faster than solar alone.
Why use an 18-watt solar panel instead of a smaller one?
In real dump trailer applications, solar panels are often mounted flat and do not operate at ideal angles all day. Because of this, smaller panels may not produce enough usable power to meaningfully offset parasitic draw.
An 18-watt panel provides a more practical level of output for trailer battery maintenance.
Is this kit a good fit for my dump trailer?
If your trailer uses a 12V battery and sits between jobs, this kit is a very practical upgrade. It is especially beneficial for dump trailers and hydraulic systems that experience battery drain while parked.
