Micro solar grid tie inverter mppt solar Smart microinverter DC 18-50V AC 120V 240V Limiter Sensor home appliance Inverter
1.The current transformer (CT) is employed to monitor the current values in an alternating current circuit and feed the data back to the grid-tied inverter. By dynamically adjusting the output in real-time, it provides approximately matched electric power to the home grid, enabling autonomous power supply and preventing excess electricity from being fed back to the grid.

2.When the real-time power consumption of household appliances surpasses the maximum output power of the grid-tied inverter, the inverter maximizes its power output, with any surplus electricity automatically supplemented by the mains power.

3.The grid-tied inverter and the current transformer are connected by dedicated cables, with the current transformer requiring installation on one of the main lines of the electrical appliance. Installation is straightforward, and it can be securely attached to either the live or neutral wire.

4.The grid-tied inverter can also collaborate with solar controllers and battery packs. During the day, solar panels charge the batteries while simultaneously supplying power to the grid-tied inverter. At night, the system relies entirely on battery power, ensuring on-demand grid-tied electricity generation throughout the day.
Breaking News:
In order to avoid the problem of MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) damage, our inverter uses high-quality MOSFETs and is equipped with an intelligent temperature control chip to effectively control the MOSFET temperature within a range of 90°C, which is within the range that MOSFET can withstand. In comparison, the MOS tube temperature of other peer companies’ inverters generally exceeds 120°C, so our product can better avoid the occurrence of MOS damage that may cause the inverter to fail to work.

Voltage Tips:
Our 18-50V grid tie micro inverter requires a starting voltage of 24V and operates in the range of 18V-39V (Vmp). Please note that the Voc of your solar panel should not exceed 50V.

Using a 12V solar panel with a Vmp of 18-20V and Voc of 20-24V is not recommended, as weak sunlight may cause the working voltage to drop below 18V, leading to unstable inverter operation and damage. Instead, we suggest using solar panels with a Vmp of 30-39V and Voc of 38-46V for optimal performance.
INSTALLATION PROCEDURES
Step 1- Attaching the Microinverters to the Racking.

a. Mark the location of the Microinverter on the rack, with respect to the PV module junction box or any other obstructions.

b. Mount one Microinverter at each of these locations using hardware ecommended by your module racking vendor.

Step 2 – Connecting the Microinverter AC cable and connectiong to AC bus cable(L-BROWN,N-BLUE,GGREEN&YELLOW) one by one, Please do NOT exceed the Maximum current of AC bus cable .

Step 3 – Connecting Microinverters to the PV Module,Please do NOT exceed PV panel(s) VOC over inverter max input voltage.

Step 4 – Install the AC Branch Circuit Junction Box,Wire the conductors of the AC bus cable. Connect the AC branch circuit junction box to the point of utility-grid Interconnection.

Step 5 – Double check all Microinverters, connectors and cables are correctly and well connected.

Step 6 – Turn ON the AC circuit breaker on each AC branch circuit of Microinverter .

Step 7 – Turn ON the main AC circuit breaker of utility-grid. Your system will start producing powerafter a 3sec safety delay period.
The current transformer must be connected to the “blue” section of the circuit and must not be connected to the “red” section; otherwise, it will result in the grid-tied inverter malfunctioning.
