KTAC TECHNOLOGY, as a professional power conversion equipment manufacturer with over 20 years of manufacturing experience since 2004, provides a full series of power inverter solutions for global residential, commercial, and industrial applications. Our power inverter lineup covers on-grid Solar Inverters, off-grid Solar Inverters, hybrid Solar Inverters, modified sine wave inverters, pure sine wave inverters, and low-frequency inverters, with power ratings from 350W to 150kW. All models adopt advanced MCU intelligent control, high-efficiency conversion topologies, and comprehensive protection functions, and are compatible with both lithium and lead-acid battery systems.
A power inverter is an essential power conversion device that converts DC power from batteries or solar panels into AC power for household appliances, office equipment, and industrial machinery. Unlike simple converters, a high-quality power inverter provides stable voltage, pure or modified sine wave output, and multiple protection functions to ensure safe and reliable operation. KTAC power inverters are widely used in home energy storage, emergency backup power, off-grid systems, RVs, marine applications, and remote area electrification.
1. Power Capacity – Calculate the total continuous load and peak surge demand. For small loads such as LED lighting, phone chargers, and small coolers, a 350W–1500W modified sine wave inverter is sufficient. For home appliances, refrigerators, and power tools, choose a 2000W–5000W pure sine wave inverter. For whole-home backup or commercial use, select 6kW–15kW hybrid or off-grid inverters.
2. Output Waveform – Pure sine wave output is identical to utility grid power and is compatible with all devices, especially motors, compressors, and sensitive electronics. Modified sine wave output is more economical and suitable for basic resistive loads.
3. Battery Voltage – Choose 12V, 24V, or 48V systems based on your battery bank. 12V systems are ideal for small portable applications; 24V systems suit medium-sized off-grid systems; 48V systems are standard for high-power residential and commercial storage.
4. Grid Interaction – On-grid Solar Inverters feed excess solar energy to the utility grid. Off-grid Solar Inverters operate independently with battery storage. Hybrid Solar Inverters combine both functions and can switch seamlessly between grid, battery, and solar power.
– Advanced high-frequency or low-frequency topologies achieve up to 98% peak efficiency and 99.9% MPPT tracking efficiency, maximizing solar energy utilization and reducing energy loss.
– High-end models deliver pure sine wave output with THD <3%, safely driving inductive loads such as motors, compressors, and precision electronics.
– LCD/LED displays, RS232/RS485/CAN interfaces, and optional WiFi monitoring enable real-time viewing of PV generation, battery status, and load power, with OTA firmware upgrade support.
– Over-voltage, under-voltage, overload, short-circuit, over-temperature, and anti-islanding protection. Some models feature IP66 protection for harsh environments.
– Supports lead-acid, AGM, GEL, lithium-ion, and LiFePO4 batteries. Built-in BMS communication enables intelligent charge/discharge management and extends battery life.
– Selected models support up to 12 units in parallel and can form three-phase systems, expanding capacity to 144kW for scalable residential and commercial applications.
– Custom enclosure color, logo printing, BMS protocol tuning, parameter presets, and packaging design are available.
– SUN series single-phase 3–6kW and three-phase 6–15kW, supporting on-grid and off-grid modes with 10ms switching. GP series single-phase 6.6–16.8kW with IP54 protection. TPW series 2–12kW with built-in MPPT controllers.
– GA series 1.2–12kW, compatible with 12V/24V/48V batteries, dual AC output, and generator input. GPEO series 6–12kW, supporting parallel and three-phase configuration.
– TPS series 500–2000VA with low-frequency transformer design, supporting AGM/lead-acid/LiFePO4. TDM-MAX series 1500–5000VA with high-efficiency pure sine wave output.
– TCI series 350–1500VA and TCI-MAX series 2000–5000VA, economical and practical for basic loads.
– SUN series on-grid models with anti-reverse current and grid feed-in capability.
– Wall-mount and floor-standing models with toroidal transformers for reliable performance and high surge capacity.
·Residential Solar Energy Storage – Store excess solar energy during the day for use at night, reducing electricity bills and reliance on the grid.
·Off-Grid and Remote Area Power Supply – Provide stable power for remote cabins, farms, and areas without grid coverage.
·Emergency Backup Power – Automatically switch to battery power during outages to keep critical loads running.
·Commercial and Industrial – Backup power and peak shaving for small factories, shops, offices, and workshops.
·Vehicle and Marine – Reliable off-grid power for RVs, boats, trucks, and mobile applications.
A: Calculate the total wattage of all loads and add a 20–30% safety margin for startup surges. For basic home backup, choose 3–5kW; for whole-home backup, choose 6–12kW; for commercial and industrial use, choose 15kW or above.
A: Pure sine wave output is identical to utility grid power and is compatible with all devices, especially motors and sensitive electronics. Modified sine wave is more economical and suitable for resistive loads, but may cause noise or overheating in some motor-driven appliances.
A: Selected models support parallel operation. The GPEO series supports up to 12 units in parallel for a total capacity of 144kW. SUN series three-phase models support multi-unit parallel configuration for three-phase systems. Please consult technical support for specific configurations.
A: Yes. Our inverters are equipped with CAN/RS485 interfaces and can communicate with mainstream lithium battery BMS systems for intelligent charge and discharge management.
A: The standard warranty is 2–3 years, with some models offering up to 5 years. Please contact our sales representative for detailed warranty policies.
