Overview

High quality sine wave AC output 12kW off grid inverter, no battery storage system, in the sunshine, the solar panels generate energy through the off grid inverter convert DC power to AC power. The grid off inverter's primary role is to provide a stable AC power supply from renewable sources and batteries, enabling self-sufficiency and independence from the conventional power grid. This type of three phase off grid inverter is essential for locations that are not connected to the traditional power grid, such as remote cabins, rural areas, or mobile setups like boats and RVs.

Features:

Two kinds of start modes: Step-down voltage start and variable frequency start. Customers can set start mode according to the type of their load.
The output voltage can be set between -40 % to +20 % of the rated voltage. And the output voltage with an accuracy ±1%.
Pure sine wave output. With a good dynamic response of less than 50MS, the waveform distortion rate is smaller, with higher conversion efficiency and stable output voltage.
Adopts a black pure aluminum radiator, which confirms the best radiating performance.
Powerful data display function. LCD can display the DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, power consumption (kWH), time and date, temperature, and fault code display.
Wide input voltage can work without battery and solar charge controller, save more cost, and with MPPT wide voltage input function, maximum use of solar power.

Details:

LCD Display

It enhances user experience by offering straightforward control and configuration options, often through a user-friendly interface. It provides clear and easy-to-read information on the inverter's status, such as voltage, current. The display can show error codes and alerts, enabling timely troubleshooting and maintenance of 12kw off grid inverter. And an LCD display consumes minimal power.

High Speed Cooling Fan

Solar power inverter generates heat during operation due to power conversion. Cooling fan improves cooling efficiency, which helps regulate the temperature and prevents overheating of off grid pv inverter. High speed fan ensures stable operation even in hot environments, reducing the risk of unexpected shutdowns. Fan can operate at varying speeds based on the inverter's load, making it energy efficient.

Multiple Protection Function

Short-circuit protection quickly detects and isolates faults, preventing damage to the inverter and other connected devices. Over-voltage and under-voltage protection ensure that the pv inverter off grid operates within safe voltage ranges, protecting the system from fluctuations. these protection functions enhance the safety, reliability, and longevity of off-grid inverters and the systems they support.

Applications:

Home Use

Remote Location

FAQ

Tips: The off grid solar inverter LCD has no display, how to solve this problem?

Fault analysis: There is no battery current input. The inverter LCD power source is supplied by the battery.

Possible reason: 1. The battery voltage is not enough. When the battery is just delivered out of the factory, it is usually fully charged. However, if the battery is not used for a long time, it will be slowly discharged (self-discharge). The off-grid system has the voltage of 12V, 24V, 48V, 96V and so on. Some applications require multiple batteries in series to meet the system voltage. If the cable is not well connected, the battery voltage will be insufficient. 2. The battery terminal is reversely connected. The battery terminal has positive and negative poles. Generally, red is connected with the positive pole and black is connected with the negative pole. 3. The DC switch is not connected or the switch has a fault.

Solution: 1. If the battery voltage is not enough, the system can't work and the solar energy can't charge the battery. Then, it is required to go to another place to charge the battery to over 30%. 2. If it is a problem with the circuit, please measure the voltage of each battery with a multimeter voltage gear. When the voltage is normal, the total voltage is the sum of various battery voltages. If there is no voltage, check whether the DC switch, terminal block, cable connector, and so on are normal one by one. 3. If the battery voltage is normal, the wiring is normal and the switch is also turned on, but the solar photovoltaic inverter still has no display, it may be the problem of the inverter. Then, it is required to notify the manufacturer for maintenance.

Much better than I expected

This 12kW off grid inverter is much better than I expected. The panel display is also good. This grid off inverter adopts pure aluminum radiator, confirms the best radiating performance. I've been using it for three months now and haven't found any problems. I will order more!

I want to know the related matters of off-grid solar inverter

1)On detection of an AC Input. Does your pure sine wave inverter charge the battery bank and also transfer the AC input directly to it's load terminal (its AC output).
2) Does your pure sine wave design have a selective or fixed (depth of discharge) DOD protection setting. If it has any, please know what its DOD protection value/percent.
The above were not stated in your specification and user manual. I am messaging you from Nigeria, where I lack consistent power supply.
