A 12kW 14kWh solar trailer power system is a mobile energy solution combining solar generation, battery storage, and power management for off-grid applications. The system features 12 kilowatts of solar photovoltaic (PV) capacity and 14 kilowatt-hours of battery storage, typically using lithium-ion or deep-cycle lead-acid batteries. Designed for portability, it powers equipment like RVs, worksites, or emergency setups through integrated inverters converting DC to AC power. Charge controllers regulate energy flow, while advanced systems enable bidirectional charging for vehicles.
Fasta Power RG72105P Product Overview
What components define a 12kW 14kWh solar trailer system?
This system integrates solar panels, charge controllers, battery banks, and inverters mounted on a mobile trailer. Solar arrays capture energy, batteries store 14kWh capacity, and inverters deliver 12kW AC output. Pro Tip: Use lithium batteries for higher cycle life in mobile applications.
The core components work synergistically: solar panels (typically 400W monocrystalline units) generate DC power regulated by MPPT charge controllers. A 14kWh battery bank—often 48V LiFePO4—stores energy, while 12kW pure sine wave inverters power 240V equipment. Thermal management systems maintain component efficiency during transport. For example, a 30-panel array (400W each) creates 12kW capacity, requiring 75m² of trailer space. Always prioritize IP65-rated enclosures for dust/water resistance in mobile setups.
How does the charging process work?
Solar energy flows through MPPT controllers to batteries, optimizing voltage conversion. Dual charging via AC/generator inputs provides backup. Pro Tip: Configure charging limits at 90% depth-of-discharge for lead-acid batteries.
During daylight, solar panels feed DC power through maximum power point tracking (MPPT) controllers, which boost efficiency by 15-30% compared to PWM models. The 14kWh battery bank charges at C/2 rates (70A for 48V systems), reaching full capacity in 5-7 sun hours. Hybrid systems allow simultaneous grid/generator charging—a 50A AC charger can replenish batteries in 3 hours. What happens during cloud cover? Automatic transfer switches engage backup sources without interrupting loads. Always install ground fault protection for trailer-mounted arrays.
| Charging Type | Rate | Time to Full |
|---|---|---|
| Solar Only | 12kW | 6-8h |
| AC + Solar | 18kW | 4h |
What applications suit this system?
Ideal for construction sites, event power, and disaster response. Delivers 12kW continuous power for tools, lighting, and HVAC. Pro Tip: Size battery capacity to cover 24h of critical loads.
These trailers power 10-15 RV air conditioners simultaneously or support welding equipment at remote job sites. During outages, they run refrigerators and medical devices for 48+ hours. Film crews use them for silent operation unlike generators. Why choose solar over diesel? Zero fuel costs and 25-year panel warranties offset higher upfront costs. Always include a 30m cable reel for flexible equipment placement.

FAQs
Yes, when paired with a transfer switch. The 14kWh capacity runs a 3kW household load for 4+ hours. Prioritize essential circuits.
What maintenance is required?
Clean panels monthly, torque connections annually, and update firmware quarterly. Lithium batteries need no watering like lead-acid.
