300 watt power inverter

Rapid shutdown capability

New electrical codes require rapid solar system shutdown so first responders or firefighters are safe from high voltage when they need to be on rooftops or servicing power lines. Microinverters comply with these rapid shutdown requirements and have this capability embedded into each module.

More Electricity

The core advantage of using 300 watt power inverter is that theoretically, you can yield more solar electricity. The reason for this is that there are slight differences in currents between solar panels. When solar panels are in a string, the current is reduced to that of the least-producing panel in the string.

Suitability for challenging installation conditions

If a solar system is facing multiple angles, meaning some panels are facing south, some east, and some west, then microinverters are the way to go. Or, if you have shading issues from trees or a large chimney, again microinverters would be best.

In these situations, the solar panels will be producing different amounts of electricity at different times of the day, but micro inverters will ensure you harvest all of the energy, while with a standard inverter you will lose some of this production.


Microinverters typically have 25-year warranties while standard inverters typically have 8 to 12 year warranties. The reliability of solar panels micro inverters was in question several years ago, but the technology now has caught up with the industry.

Panel-level monitoring

Microinverters have the ability to track the production of each individual panel, while with a standard inverter you only can track the production of the whole system.

System expansion ease

If you were to expand your system in the future, an inverter for home is simple to add one at a time. Each panel and microinverter pair can be easily added to your existing solar array without needing to worry about purchasing, siting, and installing additional string inverters.

Tips: Why is the starting voltage of the grid tie inverter higher than the minimum voltage?

In photovoltaic grid-tied inverters, there is a strange parameter, that is, the input starting voltage of the solar micro inverter, which is about 30V higher than the minimum operating voltage. For example, in single-phase inverters, the MPPT operating voltage is 70V to 550V, starting voltage is 100V. Many people wonder whether the grid tie micro inverter work or not from 70V to 100V. If it is working, the inverters need 100V to start.

In fact, the reason why the starting voltage is higher than the minimum working voltage is based on the characteristics of photovoltaic modules. Before the solar inverter starts, the components do not work and are in the open circuit state. The voltage will be relatively high. When the inverter starts, the components are in the working state and the voltage will be reduced.

If three components are connected in series, when the sun shines in the morning, the open-circuit voltage may be 90V. If it starts at this time, it may only be 60V. If it does not reach the working voltage, the inverters will stop. Only when the open-circuit voltage exceeds 100V, if it starts at this time, the working voltage will exceed 70V, and the 300 watt power inverter will work all the time.

After the solar inverters start-up, it does not mean that the inverter will have power output immediately. The control part of the inverters, CPU, screen, and other devices work first. First, the inverters are self-checked, then the components and power grid are detected. After no problem, the output of the inverters will only be achieved when the photovoltaic power exceeds the standby power of the 300 watt power inverter.
