Samlex Amer Inv/Chrgr 12Vdc 3000Watt EVO3012

What our Experts Think

• High-performance 3000W pure sine wave inverter/charger (12V DC to 120V AC) designed for serious off-grid, RV, marine, and backup power systems.
• Integrates a 130A multi-stage battery charger + inverter + 70A transfer relay in one unit, reducing system complexity and installation clutter.
• Delivers strong surge handling (up to ~9000W peak) to start demanding loads like pumps, compressors, and power tools.
• Features adaptive 4-stage charging (Bulk, Absorption, Float, Equalization) to optimize battery life and charging efficiency.
• Supports dual AC input (grid + generator) with programmable thresholds for seamless automatic switching and power prioritization.
• Includes zero-transfer synchronization, allowing near-instant switching between inverter and shore/generator power without interruption.
• Compatible with solar integration via external charge controller input, enabling hybrid solar + grid + battery configurations.
• Built-in advanced protection system (overload, short circuit, thermal, low/high battery voltage) enhances system safety and reliability.
• Designed for high-demand continuous-duty use, with robust cooling and industrial-grade construction for harsh environments.
• Ideal for full off-grid cabins, RV power hubs, and backup energy systems requiring a single integrated power center.

   
Q&A   

Q: What is the Samlex S6AEVO3012 unit?
A: It is a 3000W inverter/charger combo system that converts 12V DC battery power into 120V AC electricity, while also including a built-in battery charger and automatic transfer relay for seamless power switching.

Q: What does “inverter/charger” mean?
A: It means the unit can both invert DC to AC power AND recharge batteries from AC input (grid or generator), making it a full power management system.

Q: What is the power output?
A: It provides 3000 watts continuous output with high surge capacity for starting heavy loads like refrigerators, pumps, and power tools.

Q: What type of output does it produce?
A: It produces pure sine wave AC power, safe for sensitive electronics and appliances.

Q: What can it power?
A: It can run refrigerators, fans, lights, TVs, computers, small AC units (depending on surge), and workshop tools, as long as total load stays within limits.

Q: Is it suitable for solar systems?
A: Yes. It is commonly used in off-grid solar setups, RV systems, cabins, and backup power installations where battery + AC charging integration is needed.

Q: What input does it require?
A: It runs on a 12V battery bank, typically deep-cycle lead-acid or lithium systems designed for high current draw.

Maintenance Tips    

• Inspect DC battery cables, AC input/output connections, and terminals regularly for heat damage, corrosion, or looseness.
• Ensure all wiring is properly rated, securely tightened, and free from insulation wear or fraying.
• Keep ventilation openings, cooling fans, and heat sinks clean and unobstructed for proper thermal management.
• Install in a dry, well-ventilated area away from moisture, dust, vibration, and direct sunlight.
• Avoid exceeding inverter or charger capacity to prevent overload and internal component stress.
• Check battery bank condition frequently to ensure stable charging and consistent DC input performance.
• Inspect fuses and breakers regularly and replace only with manufacturer-specified ratings.
• Periodically test inverter output and charger functionality for stable voltage and proper operation.
• Ensure grounding is secure and compliant to reduce electrical noise and improve safety.
• Power down the unit before performing any maintenance or connection adjustments.
