2KW-6.2KW Off-Grid Solution
Experience reliable, efficient, and smart energy management with the PV1800 PRO Series, a high-performance high frequency solar inverter designed for modern residential and light commercial off-grid systems. Whether you are powering a remote farmhouse or ensuring energy independence in an urban setting, this pure sine wave solar inverter delivers stable power with advanced technical features that professional installers and distributors trust.
Smart Energy Management with Dual Output
The standout feature of the PV1800 PRO is its dual output capability (available on most models). This allows for sophisticated load management, prioritizing your critical appliances (Main Load) while managing secondary devices (Second Load). In scenarios where battery levels are low, the system intelligently optimizes power distribution, a crucial requirement for residential ESS solutions and mission-critical backup power.
High-Voltage PV Input for Efficient Installation
Engineering excellence is at the core of the PV1800 PRO. With a maximum PV array open circuit voltage reaching up to 500VDC, this MPPT solar inverter supports high-voltage strings. This means you can connect more panels in series, significantly reducing cable costs, simplifying installation, and increasing the overall inverter efficiency (peaking at 90%~93%).

Versatile, Battery-Optional Operation
While traditional off-grid systems often require a significant upfront investment in energy storage, our intelligent architecture allows the system to power your loads directly from the solar panels during daylight hours, even without a battery bank connected.
This "Battery-Optional" flexibility is a game-changer for several reasons:
- Phased Investment: Ideal for budget-conscious projects, allowing users to install the solar array and inverter first, then add LiFePO4 batteries later as their energy needs or budget grow.
- System Reliability: In the event of a battery maintenance cycle or unexpected cell failure, the inverter ensures your critical devices remain operational using available PV power or utility input.
- Cold-Start Capability: The system is engineered to restart automatically from solar energy alone, ensuring that even after a full system shutdown, your power restores as soon as the sun rises.
For solar energy integrators, this feature offers a high-value selling point, providing end-users with a lower entry barrier to clean energy while maintaining a clear upgrade path to a full residential ESS solution.
FAQ
Q: Is the 6.2KW model capable of handling high-starting torque for motors or pumps?
A: Absolutely. The PV18-6248 PRO provides a surge power capacity of 12,400W (200% of rated power) for 5 seconds. This is specifically designed to handle the high inrush current of air conditioners, water pumps, and power tools.
Q: Does this inverter support communication with Lithium (LiFePO4) batteries?
A: Yes. The unit includes dedicated RS485 and CAN communication ports. We have pre-configured protocols for major battery brands, ensuring the BMS (Battery Management System) and inverter accurately sync SOC (State of Charge) and voltage data.
Q: What happens if the solar power is insufficient? Does it switch to the grid seamlessly?
A: The transfer time is 10ms (UPS mode), which is fast enough to prevent computers or servers from rebooting. The system intelligently blends power from Solar, Battery, and Utility based on your set priority (SUB, SBU, or USB modes).
Q: Is there a mobile app for remote monitoring?
A: Yes. By adding an optional Wi-Fi or GPRS plug, you can monitor real-time production, battery status, and load consumption via our mobile app or web portal from anywhere in the world.
Q: What protection features are built into the hardware?
A: The system includes full protection for overload, short-circuit, deep discharge, and overcharge. The PCBA is also treated with a conformal coating to resist dust and moisture in humid environments.
