How to Get Solar on Your Horse Float or Horse Truck

Why Solar Makes Sense for Horse Floats

Horse floats remain stationary for extended periods at events without power access, unlike daily-moving caravans. They function as mobile bases with cooking areas, sleeping quarters, and social hubs during competitions. Solar enables operation of refrigeration for medications, phone/radio charging, LED lighting for early morning or evening horse care, and ventilation systems.

Power Needs Assessment

Before sizing systems, calculate actual consumption. A typical competition setup includes:

  • Refrigeration: 2-4A continuous (48-96Ah daily)
  • LED lighting: 5-15A for 4-6 hours
  • Water pumps: 5A intermittent use
  • Device charging: 10-20Ah daily
  • 12V fans: 2-5A each

Most horse float solar systems work well with 200-400 watts of panels and 200-400Ah of lithium battery storage, handling typical loads for 2-3 days without sunlight.

Solar Panel Options

Horse floats present unique mounting challenges with roof interruptions from vents, antennas, and loading equipment.

Fixed Panel Installation

Fixed monocrystalline panels offer the best value and performance, mounted using aluminium Z-brackets or caravan-specific systems. Consider float height for overhead restrictions.

Flexible Solutions

Where roof space is limited or curved, flexible panels work effectively. Sunman eARC technology manages partial shading better than traditional panels -- useful when parked under trees.

Battery Systems

Horse floats experience significant vibration and movement, making lithium batteries the clear choice over traditional AGM. LiFePO4 batteries handle constant motion better and provide more usable capacity in limited space. A 200Ah lithium battery typically provides 2-3 days of power for essential loads.

Essential Components

Solar Charge Controller

MPPT controllers maximize charging efficiency. The Victron SmartSolar range offers Bluetooth monitoring -- perfect for checking system status from anywhere around the float.

Inverter Selection

Size inverters based on largest AC loads. 1000W pure sine wave inverters handle most appliances; 2000W units run larger equipment like horse clippers or pressure washers.

DC-DC Charging

Install DC-DC chargers to charge house batteries while driving, ensuring arrival at events with full capacity regardless of travel weather.

Installation Considerations

Use IP68 cable entry glands to prevent roof water ingress. Route DC wiring away from horse interference areas using conduit or cable trays. Any 240V wiring requires a licensed electrician. DC systems under 60V can typically be installed by competent DIYers, pending local regulations. Install appropriate circuit breakers and fuses for safety.

Real-World Setups

Customers often start with basic configurations and expand as needs grow:

  • Weekend warrior: 200W panel, 200Ah battery, 1000W inverter
  • Extended stay: 400W panels, 400Ah battery, 2000W inverter
  • Professional competitor: 600W+ panels, 600Ah+ battery bank with monitoring

Maintenance and Monitoring

Horse floats accumulate dust quickly. Clean panels regularly and check connections for corrosion. Battery monitors track system performance and identify issues early. Remote monitoring systems sending phone alerts prove useful when floats are parked during competitions.
