3. Lifelong Product Support

Beyond the warranty period, we continue to supply genuine parts at competitive prices, ensuring your system remains operational for years to come. Parameter Description:

1. 100% pure sine wave AC output.

2. Dual AC output, main load output 10000W, second load output 5000W. The second output can be controlled by scheduling on/ off time, setting cut-off voltage or SOC, and discharging time.

3. With twice the surge power (20000W), it effortlessly starts inductive loads that have high inrush currents.

4. Power Factor: 1

5. No-load power consumption is 30W~50W.

6. Max. PV input voltage: 500V

7. Wide MPPT operating voltage range: 90V~450V

8. MPPT start voltage: As low as 90V (for 48V battery system). This extends your daily power generation by capturing energy earlier in the morning and later at dusk. All-in-One Solar Inverter
Infinisolar MEXP900-10048 inverter is a 10KW 48V to 220V/230V/240V single-phase off-grid all-in-one solar Inverter, with built-in 150A MPPT charger and 150A AC charger. Combining solar, AC utility/ generator, and battery to create an uninterruptible power supply. Dual MPPT & Wide PV Input
Built-in dual 150A independent MPPT controller, maximises energy from every panel group even with shade, different angles, or mixed brands. Independent optimisation boosts yields up to 25% while comparing to single-track systems. Smart Dual AC Output
Inverter output power to critical and non-critical loads with priority-based energy allocation, ensuring the uninterrupted operation of important electrical appliances. The maximum power of the second load is limited to 5000W. Multiple Control Modes of Dual AC Output
Achieving fully automated and intelligent control of dual-load output through dynamic power allocation and four preset second load output modes. Configure output modes based on battery voltage, battery SOC, discharge duration, or start/ end time. Support to Work Without Battery
Battery-less operation enables direct solar-to-load power conversion, harnessing solar energy for immediate appliance operation. And in this scenario, the rated output power is up to 10000W, which is the same as the inverter's full rated power. High Compatibility With Various Batteries
The inverter features wide battery compatibility, allowing connection to 48V Lead-acid (AGM, GEL, FLA, SLA.) batteries, Lithium (LiFePO4) batteries and user-defined batteries. Dual Lithium Battery Auto Activation
When the lithium battery is dormant, the mains AC power and photovoltaic can automatically detect its status and activate it back to working state.The dual activation function ensures the dormant lithium battery can be activated during both day and night. Smart Charging Algorithm For Different Batteries 
Compared to other inverters, we have adopted a 3-step charging algorithm for lead-acid battery, a 4-step charging algorithm for Lithium battery, which unlocks 30% longer battery life with precision parameter tuning. Segmented Charging & Discharging Modes
There are three battery charging modes that are optional, i.e. only solar, solar priority, and utility & solar hybrid charging; and four load output working modes (SUB, SBU, SOL, UTI) are available, to meet different application requirements. Optimisation Solar Supply Scheduling
Featuring two solar supply modes: load priority and battery priority. Load priority mode can directly use solar energy to power home appliances for optimal self-consumption. Battery priority mode will charge the battery first for reliable backup energy. Let you align solar flow with your specific energy requirement. Power Saving Mode Supported
Power saving mode is designed to reduce no-load loss. If it is enabled and the load is less than 50W, the inverter output will be switched off. The inverter will resume output when the enclosure switch is pressed to "OFF" and then pressed to "ON". Max Parallel 6 Units
Support parallel 6 units up to 60KW power output, you will get 230V single phase or 380V 3-phase support (more than 3 units in parallel), increasing the inverter power and surge capacity. The package includes 1pcs built-in parallel card and 1pcs parallel cable. Seamless AC & DC Auto Switching
Can work like UPS. 10ms/20ms AC & DC auto-switching ensures uninterrupted power for critical loads during grid transitions. Pure Sine Wave Solar Inverter
10KW rated power, dual AC 230V pure sine wave output, suitable for 98% of household and office appliances such as refrigerators, lamps, televisions, fans, air conditioning, and other AC loads. Wired PC Monitoring
Through the USB-B interface that integrates RS485 functions and a communication cable, wired PC monitoring of inverters can be realised. The communication cable is included in the package list. (Note: PC monitoring and Wi-Fi monitoring cannot be enabled at the same time.) WiFi Remote Monitoring
Unlike other inverters on the market, we use the USB-A interface that integrated RS485 communication function. This unique configuration enables seamless connection to an external Wi-Fi module, providing independent remote monitoring capabilities. Users can effortlessly access real-time device status or adjust parameters anytime & anywhere through a mobile app or PC web. (Note: The WiFi module is optional.) Colour LCD Display & LED Indicators
With function buttons and an LCD, indicating the operating status and input/output power information, allowing you to set parameters like battery charging current, working modes, etc. Advanced Communication and Integration
Through the built-in communication protocol and multiple independent communication interfaces (RS485, CAN, USB, WiFi, AGS), seamless communication between the inverter and external monitoring devices, generators and lithium batteries can be easily achieved. BMS Communication With LI Battery
The inverter is built with BMS protocols for seamless lithium battery communication. Compatible with MUST and PYLON lithium batteries via CAN protocols. 360 All Round Protections
The hybrid solar inverter 360 provides comprehensive protection with various features, such as short circuit protection, over-voltage and under-voltage protection, overload protection, and reverse polarity protection. These safety measures significantly enhance the security of your electrical circuits and usage.
