Battery Maximizer Kit – 25W Solar Panel + 18A Panel Mount Charger

Keep your dump trailer battery charged and ready with the Primary Mover Battery Maximizer Kit. This upgraded system combines a 25-watt solar panel with an 18-amp panel mount charger to deliver stronger charging performance for 12V dump trailers, truck beds, and hydraulic power units.

Dead batteries are one of the most common issues in dump trailers and hydraulic systems. Parasitic draw from remotes, solenoids, and control modules slowly drains your battery—even when not in use. This kit is designed to help offset that loss and keep your system ready to work.

When connected to shore power (120V AC), the 18-amp panel mount charger provides fast, reliable battery charging. When you're off-grid, the 25W solar panel delivers increased output compared to smaller panels, helping offset parasitic load and maintain your battery more effectively over time.


What’s Included

  • 25-Watt Solar Panel
  • 18-Amp Panel Mount AC Charger (120V Input / 12V Output)
  • Designed for 12V battery systems on dump trailers and hydraulic equipment

Why This Kit Is Beneficial

  • Faster Shore Power Charging: 18A output allows quicker battery recovery when plugged in.
  • Higher Solar Output: 25W panel provides stronger maintenance charging compared to smaller panels.
  • Offsets Parasitic Draw: Helps prevent battery drain while your trailer sits idle.
  • Reduces Downtime: Keeps your dump trailer ready instead of needing a jump.
  • Improves Battery Life: Helps reduce deep discharge and sulfation buildup.

Key Features

  • 25W Solar Panel – Increased output for better real-world performance
  • 18A AC Charger – Strong shore power charging for faster recovery
  • 12V System Compatible – Built for dump trailers and hydraulic power units
  • Dual Charging Solution – Solar maintenance + AC charging
  • Trailer-Grade Components – Designed for work environments

Recommended Applications

  • Dump trailers with moderate to heavy parasitic draw
  • Truck dump bed conversions
  • Hydraulic power units
  • Trailers stored for extended periods
  • Customers wanting stronger solar + faster AC charging

Important Performance Expectations

The 18-amp AC charger is the primary solution for fully recharging your battery quickly. The 25W solar panel is designed to help offset parasitic draw and provide slow charging over time.

Solar charging is extremely beneficial for maintaining battery health, but it is not intended to replace high-output charging when recovering a deeply discharged battery.

Frequently Asked Questions

Click to expand

Why do I need this kit?

Dump trailers and hydraulic systems constantly experience parasitic battery drain. This kit helps prevent dead batteries by combining shore power charging and solar maintenance charging.

Will the solar panel charge my battery?

Yes, with realistic expectations.

The 25W solar panel provides stronger output than smaller panels and is ideal for maintaining battery charge and offsetting parasitic draw over time. It is not designed for rapid charging like the AC charger.

What is parasitic draw?

Parasitic draw is the small amount of power your system uses even when turned off, such as remotes, solenoids, and control modules.

Over time, this will drain your battery if not offset.

Why is the 18-amp charger important?

The 18A panel mount charger allows for faster and more effective battery charging when connected to shore power, reducing downtime and ensuring your trailer is ready when needed.

Why use a 25W solar panel instead of a smaller one?

In real trailer applications, solar panels are mounted flat and lose efficiency. A 25W panel provides more usable output, helping better offset parasitic load and maintain battery voltage over time.

Is this kit right for my dump trailer?

If your trailer uses a 12V battery and sits between jobs or has noticeable battery drain, this upgraded kit is an excellent solution.
