FAQ

Can we visit your factory?

Surely, I will arrange the trip basing on your business schedule.

Can you do OEM for us?

Yes, we can.

Can you help us install the module if we cooperate with you?

We haven’t entered into installation sector, but we have the plan in near future.

The solar photovoltaic micro inverter is a device which converts DC from a single solar cell component to an alternating current.

Micro inverter to convert the DC power is transformed from a single solar AC module, each solar battery module equipped with inverter and converter function. Each component can be separately in the current, so it is known as ""micro inverter"".

The micro inverter can achieve maximum power point tracking (MPPT) in the panel stage, and has the advantage over the centralized inverter. This can be carried out by optimizing the output power of each module, making the overall maximum output power.

In addition, and communication function combination, but also can be used to monitor the status of each module, to detect the failure of the module.

According to whether there is energy storage battery, it is divided into grid connected micro inverse and off grid micro inverse. According to the output voltage, it can be divided into single phase micro inverse and three-phase micro inverse.

Micro inverter technology proposed inverter directly with a single PV module integration, for each PV module with a single with AC / DC conversion function and the maximum power point tracking function of the inverter modules, electricity generated in the PV module can directly convert the AC power supply AC loads or transmitted to the grid.

From the current point of view, the advantages of micro inverter is very obvious. In practical applications, if the group of series inverter failure, it will cause thousands of watts of the battery plate can not play a role, and the impact of the micro inverter fault is quite small.
