Product Description
VEICHI SIS series off-grid inverter is suitable for the household photovoltaic energy storage system. DC power generated by solar panels is stored in the battery through the inverter. When electricity is needed, it is first supplied by solar panels. If the light intensity cannot support the operation of solar panels, the inverter will convert the DC power of the battery into a three-phase power for home load. If the battery power is not enough, it can be quickly switched to power grid to supply power.
SIS series off-grid inverter has a detachable LCD control module and a variety of communication functions. It can be remotely operated through the mobile phone APP, which is convenient and fast. It can output pure sine wave, run stable and reliable. Replaceable fan design enables customers to maintain safety and convenience.
1. Pure sine wave output;
2. Self-consumption and Feed-in to the grid;
3. Built-in MPPT solar charger;
4. Programmable supply priority for PV, Battery or Grid;
5. User-adjustable charging current and voltage;
6. Programmable multiple operation modes:Grid-tie, off-grid and grid with backup;
7. Detachable LCD panel;
8. Built-in WiFi for mobile monitoring (APP is available);
9. Supports USB on-the-go function;
10. Reserve BMS communication;
11. Parallel operation up to 9 units;
>>> Detachable LCD Control Module with Various Communications
This detachable LCD control module can be turned to remote panel. Users can install the LCD panel in accessible area away from inverter up to 20 meters.
>>> Supports USB On-the-Go Function
VM III series supports USB On-the-Go function to facilitate data upload/download.
>>> Intergrated WiFi Interface With Mobile App
VM III series is integrated WiFi interface ready for mobile monitoring. Mobile monitoring can be carried out through mobile applications in both iOS and Android. Users can track the history of the unit information such as energy generation and change parameter settings timely.
>>> Reserved Communication Port (RS-485,CAN-BUS or RS-232 for BMS)
This third generation inverter is reserved communication port for BMS. For the detailed information, please contact sales directly.
>>> Replaceble Fan Design
VM III series is designed with replaceable fan. It will simplify the maintenance and reduce the maintenance cost.
SIS series is widely used in the energy storage system of residential and power-deficient areas.
