A1 Series APU: High-Capacity All-in-One Solution

Overview

The A1 Series is our flagship electric APU system, designed for drivers who want maximum runtime with minimum complexity. It features a single large-capacity battery (460Ah or 560Ah) paired with powerful air conditioning - no multiple batteries to manage, just simple plug-and-play operation.

Key Features

Single Large Battery Design:

• One integrated 460Ah or 560Ah LiFePO4 battery pack
• No need to connect multiple batteries
• Simplified installation and maintenance
• All battery cells balanced and managed as one unit

Two Air Conditioner Options:

• A11 Model: 10,000 BTU cooling capacity
• A12 Model: 15,000 BTU cooling capacity

Runtime Performance:

• 6-10 hours of continuous air conditioning on a full charge
• Covers a full 10-hour rest period with margin
• Consistent cooling power throughout the night

A11 Air Conditioner (10,000 BTU)

Best For:

• Standard sleeper cabs (36"-48" size)
• Most regions across the U.S.
• Teams of 1-3 drivers

Power Consumption:

• Approximately 50-90Ah per hour at maximum cooling
• 7-9 hours runtime with 460Ah battery
• 8-11 hours runtime with 560Ah battery

Cooling Coverage:

• Efficiently cools 80-120 cubic feet
• Maintains 68-72°F in typical summer conditions

A12 Air Conditioner (15,000 BTU)

Best For:

• Larger extended sleeper cabs
• Most regions across the U.S, with optimized performance for hot climates (Southern & Southwest states)
• More team drivers or extended cab space

Power Consumption:

• Approximately 65-100Ah per hour at maximum cooling
• 6-8 hours runtime with 460Ah battery
• 7-10 hours runtime with 560Ah battery

Cooling Coverage:

• Efficiently cools 120-180 cubic feet
• Maintains comfortable temperatures even in 100°F+ conditions

Battery Capacity Comparison

460Ah Battery Configuration

Pros:

• Lower initial cost
• Lighter weight (still lighter than equivalent lead-acid)
• Adequate for most applications
• 6-8 hours runtime with A11 air conditioner

Recommended For:

• Drivers in moderate climates
• Budget-conscious operations

560Ah Battery Configuration

Pros:

• Extended runtime (10 hours)
• Extra capacity margin for hot nights
• Better for larger air conditioners
• Handles additional loads (inverter, TV, etc.)

Recommended For:

• Hot climate operations
• Drivers who want maximum peace of mind
• Those running additional electronics overnight

Installation Advantages

The A1 Series uses a backpack-style split design:

Installation Process:

• Drill mounting holes in the rear wall of the sleeper cab
• Mount the air conditioner unit on the exterior
• Route refrigerant lines and wiring through the wall
• Mount battery inside the sleeper or under the bunk; custom brackets are also available for external mounting
• Connect electrical wiring

No Roof Damage:

• Unlike rooftop units, no permanent roof modifications required
• No risk of roof leaks
• Easier to install and remove
• Better for resale value

Installation Time:

• Typically 3-5 hours for professional installation
• DIY-friendly for mechanically inclined operators

Best Use Cases

Long-Haul Operations:

• Coast-to-coast routes with nightly sleeper use
• Drivers who need reliable 10-hour break cooling
• Operations with consistent daily driving (battery recharge)

Solo Owner-Operators:

• Simple operation - one battery to manage
• Predictable runtime every night
• Quick ROI through fuel savings

Hot Climate Routes:

• Southern states, Southwest, summer operations
• Pair with 560Ah battery for extra capacity
• A12 model recommended for extreme heat

Maintenance & Reliability

Battery Maintenance:

• No maintenance required
• Built-in battery management system
• Self-balancing cells
• Temperature-controlled charging

Air Conditioner Maintenance:

• Annual filter cleaning (simple DIY)
• Check refrigerant levels every 2-3 years
• Inspect electrical connections annually

Expected Lifespan:

• Battery: 3,000+ cycles (8-10 years typical)
• Air conditioner: 8-10 years with basic maintenance

Technical Specifications Summary

Cost Comparison vs. Idling

Daily Idling Cost (10 hours at 0.8 gal/hr):

• 8 gallons diesel × $3.50/gallon = $28 per night
• Annual cost (250 nights): $7,000

A1 Series Electric APU:

• Zero fuel cost during rest periods
• Payback period: Approximately 14-18 months
• Annual savings: $7,000+

Ordering Guidance
