Working Principle
Key Advantages
- High-Efficiency MPPT Solar Charging：Built-in 100A MPPT solar charger supports up to 5000W PV array power and 60–500Vdc wide voltage range, maximizing solar energy harvest with up to 96% peak conversion efficiency from PV to AC output.
- Battery-less Operation & Flexible Power Priority：The inverter can run directly from solar PV or utility grid without a battery connected, reducing initial system cost. Three output priority modes — SUB, SBU and SUF — allow users to freely define the energy source sequence.
- LiFePO4 Battery Compatible with Smart Activation：RS485 communication enables seamless integration with LiFePO4 battery packs. The built-in lithium battery activation function automatically wakes up dormant batteries via PV or utility power, ensuring reliable system startup.
- Pure Sine Wave Output with Strong Surge Capacity：Delivers clean 220V/230V pure sine wave power with 22000VA surge capability and 3:1 crest factor, safely handling inductive and capacitive loads such as motors, compressors and refrigerators without waveform distortion.
- Rugged Design for Harsh Environments：Detachable dust cover, -10°C to 55°C wide operating temperature range and efficient heat dissipation ensure stable long-term operation in dusty, high-temperature or humid field conditions; optional WiFi module enables remote monitoring.
Application Scenarios
- Residential Solar Energy Storage Systems：Designed for home rooftop PV installations, this 3.6KW hybrid inverter converts solar power into stable 220V AC electricity for daily household loads, while storing surplus energy in 24V lead-acid or LiFePO4 batteries for nighttime use.
- Off-Grid Cabins & Remote Rural Houses：With support for battery-less operation and a wide PV input range of 60–500Vdc, it delivers reliable standalone power for remote houses, mountain cabins and rural sites where utility grid access is unavailable or unstable.
- Small Commercial Shops & Office Spaces：The 3.6KW continuous output and 22000VA surge capacity comfortably power small retail shops, offices and kiosks, protecting computers, POS systems and lighting from grid outages and voltage fluctuations.
- Backup Power for Small-Scale Industrial Equipment：Featuring pure sine wave output and a 3:1 crest factor, the inverter safely drives inductive loads such as small pumps, motors and refrigeration units, making it suitable for light industrial workshops and agricultural facilities.
Typical Configurations
Step 1 - Size the PV array. Plan up to 5000W of panels within the 60-500Vdc MPPT window, keeping the open-circuit voltage below 500Vdc.
Step 2 - Choose the battery bank. Match a 24V lead-acid or LiFePO4 bank; battery-less operation is possible when only daytime solar or grid supply is required.
Step 3 - Set the priority mode. Select SUB, SBU or SUF according to whether solar, battery or utility should serve the load first.
Step 4 - Plan monitoring and environment. Use RS485 for battery BMS communication, optional WiFi for remote monitoring, and install within -10°C to 55°C at IP21.

FAQ
Can I run a 2000W inverter off a car battery?
Yes for short periods, but it is not recommended for continuous high-power use. Car batteries have limited capacity and can be drained quickly; a deep-cycle battery is better.
How long will a 200Ah battery run a 500W inverter?
Approximately 3.5–4 hours (assuming a 12V system, 80% depth of discharge, and 85% efficiency).
How many batteries do I need for a 500watt inverter?
Typically one 12V 100Ah battery is enough, depending on the desired runtime.
How many batteries do you need to run a 3K inverter?
A 48V system is recommended: 4 × 12V 100Ah batteries connected in series to give 48V 100Ah, or increase capacity for longer runtime.
How long will a 200Ah battery last with a 1000W inverter?
Approximately 1.5–1.9 hours (12V system, accounting for efficiency and depth of discharge).
What priority modes are available?
Three output priority modes are available - SUB, SBU and SUF - letting users define whether solar, battery or utility supplies the load first.
Which battery chemistries are supported?
The inverter works with 24V lead-acid and LiFePO4 battery banks; RS485 communication and automatic lithium activation support LiFePO4 packs with BMS.
What information should I provide for a quotation?
Please provide the required power rating, PV array size and voltage, battery type and voltage, load list, quantity and destination country.
