Important Note:
This is a multi-functional off grid photovoltaic inverter, integrated with MPPT photovoltaic charging controller, high-frequency pure sine wave inverter and UPS functional module, which is very suitable for off grid backup power supply and self use system. The design of high-frequency transformer enables the machine to provide reliable power conversion in a small size. This inverter can also operate in battery free mode.
The WiFi/GPRS module is a plug and play monitoring device installed on the inverter. With this device, users can monitor the operation status of the photovoltaic system anytime, anywhere through mobile phones or websites.

Can be accessed to a variety of household appliances and office loads, power tools, industrial equipment, and electronic audio and video equipment, including refrigerators, lamps, televisions, fans, air conditioning and other AC loads
1. This is a wide voltage Hybrid inverter, The voltage that starts to connect to the solar panel must be above 150V for the Hybrid inverter to work normally. Means you can connect solar panels in series, saving you the cost of buying wires
The whole system also need other devices to achieve complete running such as PV modules, generator, or utility grid.
Parallel operation up to 6 unit (only with battery connected)
This inverter can be used in parallel with two different operation modes.
1. Parallel operation in single phase with up to 6 units.
2. Maximum 6 units work together to support 3-phase equipment. Four units support one phase maximum.
WARNING!
All inverters must be connected to the same batteries and ensure each group of cables from the inverters to the batteries in the same length.
Important Note:
The ground and neutral conductors of the SPF 3500 ES are not connected together and the enclosure does not become part of the ground return.
Test Methods: Use the multimeter’s beep gear to measure whether the neutral wire and the ground wire are connected together, if they are connected together, it will make a “beep” sound. If there is no sound, there is no connection.
