Key Features
Pure Sine Wave Output with Superior Starting Power: True pure sine wave AC power identical to household mains electricity enabling safe operation of sensitive electronics and appliances. Greater starting power than modified sine wave inverters ensures reliable startup of lightweight household appliances with motors and compressors. Eliminates buzzing, transformer overheating, and interference. Critical for laptops, CPAP machines, appliances with electronic controls, and motor-driven devices.
1100W Continuous / 2200W Surge Capacity: Reliable 1100W continuous power suitable for household appliances including coffee makers, small microwaves, portable fridges, TVs, power tools, and multiple devices simultaneously. 2200W surge capacity handles startup current spikes from motors, compressors, and inductive loads. More than double the capacity of 500W inverters enabling broader appliance compatibility.
Dual AS/NZ Approved 240V Sockets: Standard Australian three-pin power outlets accepting any household plug. AS/NZ approval ensures compliance with Australian electrical safety standards. Dual sockets enable simultaneous operation of multiple devices—run coffee maker while charging laptop or power multiple appliances. No adapters required for Australian appliances.
USB Charging Ports: Integrated 2.1A USB-A and 21W USB-C ports for direct device charging without separate adapters. USB-A charges smartphones, tablets, cameras, and USB-powered devices. 21W USB-C provides fast charging for modern phones and devices exceeding standard 18W charging speeds. Eliminates need for USB wall adapters reducing clutter.
Remote LCD Display with Monitoring: Separate remote display showing real-time battery voltage, power consumption (watts), and load capacity. Mounts in convenient dash or console location enabling monitoring without accessing inverter installation location. Battery voltage tracks auxiliary battery state, power consumption shows energy usage, load capacity indicates available power preventing overload.
Heavy-Duty Wiring Kit Included: Complete wiring kit with battery lugs and 1100mm 16mm² battery cable for direct auxiliary battery connection. Upgraded 16mm² cable (versus 8mm² on smaller inverters) handles higher current draw from 1100W loads—1100W at 12V equals approximately 100A draw requiring substantial cable gauge preventing voltage drop and overheating. Battery lugs ensure secure connection. 1100mm length suits typical installations.
Australian AS4763 Certification: Designed and certified to Australian standard AS4763 for inverters ensuring electrical safety compliance. Certification required for legal installation in caravans and RVs, insurance compliance, and electrical safety inspections. Demonstrates commitment to Australian market requirements versus generic international-spec inverters.
Comprehensive Protection Features: Overload shutdown protects inverter and devices when load exceeds 1100W capacity. Over-temperature protection monitors internal temperature shutting down if overheating. Low voltage alarm warns of excessive battery discharge protecting auxiliary battery. Reverse polarity protection prevents damage from incorrect wiring. Protections ensure safe reliable operation.
Compact Silent Operation: Compact dimensions suitable for permanent installation or portable use. Silent operation produces zero audible noise or electrical interference—no cooling fans, transformer hum, or electromagnetic interference. Suitable for bedroom installations (CPAP machines) or noise-sensitive applications unlike loud modified sine wave inverters.
Projecta 50-Year Australian Heritage: Designed and engineered in Australia by Projecta's experienced team for harsh Australian conditions. 50-year history supplying battery chargers, inverters, and power products. State-of-the-art development facilities researching global technology and designing products from ground up. Quality construction and Australian support ensuring long-term reliability.

Frequently Asked Questions
Q: What appliances can I run with 1100W capacity?
A: 1100W suitable for coffee makers (800-1000W), small microwaves (700-900W), portable fridges (100-150W), LED TVs (50-200W), laptops (60-100W), power tool battery chargers (100-300W), hair dryers on low setting (600-800W), electric kettles (1000W), phone chargers (10-20W), and combination of smaller devices. Cannot run: large microwaves (1200W+), toasters (1500W+), air conditioners (1000-2000W+), or hairdryers on high (1500W+). Check appliance wattage label—sum of all simultaneous loads must not exceed 1100W. Starting surge for motor-driven appliances (fridges, power tools) handled by 2200W surge capacity.
Q: How long can I run a 500W coffee maker from a 200Ah battery?
A: Approximately 3-4 hours from fully charged 200Ah AGM battery (accounting for 50% discharge limit). Calculation: 200Ah battery × 12V = 2400Wh capacity. Inverter efficiency approximately 90% = 2160Wh usable. AGM battery 50% discharge limit = 1080Wh usable. 500W coffee maker = 1080Wh ÷ 500W = 2.16 hours theoretical. Coffee maker typically operates 5-10 minutes per brew cycle—approximately 20-40 brew cycles possible. Lithium batteries allow deeper discharge (80-90%) providing longer runtime. Monitor battery voltage on LCD display—stop use when voltage drops to 11.5-12V preventing AGM battery damage.
Q: Can I run this from my starter battery for short periods?
A: Not recommended—1100W draws approximately 100A from 12V battery (accounting for losses) rapidly draining starter battery. Even short operation risks insufficient charge for starting vehicle particularly if battery partially discharged or cold weather. Always connect to auxiliary battery with proper isolator (VSR or DC-DC charger) protecting starter battery. Emergency situations only—run engine simultaneously maintaining starter battery charge, limit duration to minutes not hours.
Q: What size battery cable do I need if mounting farther than 1100mm?
A: Maintain 16mm² minimum cable gauge regardless of length. Longer cable runs require larger gauge preventing voltage drop—consult voltage drop calculator for specific length and current. Example: 2-meter run at 100A draw may require 25mm² cable maintaining acceptable voltage drop. Voltage drop degrades inverter performance reducing output voltage and power. Install inverter as close to battery as practical minimizing cable length. Maximum recommended cable length approximately 3 meters with 16mm²—longer runs require professional electrical design.
Q: Why is pure sine wave better than modified sine wave for this power level?
A: Pure sine wave critical at 1100W level powering household appliances with electronic controls, motors, and sensitive components. Modified sine wave causes: microwave ovens malfunction or fail, coffee makers with electronic controls operate incorrectly, power tools run hot and inefficiently, audio equipment produces buzzing, laptop power supplies overheat, and reduced appliance lifespan. Greater starting power of pure sine wave ensures reliable motor starting in fridges, power tools, and compressors—modified sine wave may fail to start these loads despite adequate wattage rating. Pure sine wave essential for modern appliances—modified sine wave acceptable only for basic resistive loads (simple heaters, incandescent lights).
