Infinisolar MEXP900-12048 inverter is a 12KW 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 offer an uninterruptible power supply.

Built-in dual 150A independent MPPT controller, maximise energy from every panel group—even with shade, different angles, or mixed brands. Independent optimization boosts yields up to 25% compared to single-track systems.

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 6000W.

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.

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 12000W, which is the same as inverter full rated power.

The inverter features wide battery compatibility, allowing connection to 48V Lead-acid (AGM, GEL, FLA, SLA...) batteries, Lithium (LiFePO4) batteries and user-defined batteries.

When the lithium battery is dormant, the mains AC power and photovoltaic can automatically detect its status and activate it back to working state. Dual activation function ensures the dormant lithium battery can be activated during both day and night.

Compared to other inverters, we have adopted a 3-step charging algorithm for lead-acid battery, a 4-step charging algorithm for Lithium battery, unlocking 30% longer battery life with precision parameter tuning.

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.

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 battery first for reliable backup energy. Let you align solar flow with your specific energy requirement.

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".

Support parallel 6 units up to 72KW power output, you will get 230V single phase or 380V 3-phase support (more than 3 unit in parallel), increasing the inverter power and surge capacity. The package includes 1pcs built-in parallel card and 1pcs parallel cable.

Can work like UPS, 10ms/20ms AC & DC auto-switching ensures uninterrupted power for critical loads during grid transitions.

12KW 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.


Through the USB-B interface that integrates RS-485 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.)

Unlike other inverters on the market, we use the USB-A interface that integrates RS-485 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.)


With function buttons and an LCD display, indicating the operating status and input/output power information, allowing you to set parameters like battery charging current, working modes etc.


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.

The inverter is built with BMS protocols for seamless lithium battery communication. Compatible with MUST and PYLON lithium batteries via CAN protocols.

The hybrid solar inverter offers 360° 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.
