What’s the maximum power that can be configured on the DC side of your inverter?

The DC side of the Hopewind single-phase inverter can be configured with 1.1-1.2 times the rated power, and the three-phase inverter can be configured with 1.3 times or more the rated power. To avoid power loss on the DC side for a part of the time, it is generally recommended to design based on 1.2 times the rated power.

In addition, it is necessary to configure different super proportions according to different component specifications, such as high-power components of 182 and 210 specifications.

Can your collector be used on other inverters? Or can other collectors be used in your inverter?

Yes, as long as the protocols match and are compatible.

Why should the shell of the series PV inverter be grounded (PE), and what are the requirements of the cable?

(1) When the equipment leaks electricity, its shell, bracket and other metal parts connected to it will present voltage; When a person accidentally touches these live parts, an electric shock accident may occur; The purpose of grounding is to ensure the normal operation of equipment and personal safety.

(2) For ground wire, prepare a grounding special copper cable with a diameter of not less than 16mm2.

What are the requirements for the installation environment and reserved space of the series PV inverter?

(1) It shall be installed in a well ventilated place;

(2) Avoid exposure to direct sunlight, rain and snow;

(3) It is recommended to install it in a sheltered place, and install an awning in case of failure to meet the requirements;

(4) 0.5m space shall be reserved on the left and right sides of the inverter, and 0.3m space shall be reserved on the up and down sides;

(5) 1m space shall be reserved at the front of the inverter;

(6) Promote heat dissipation of the inverter and improve maintenance efficiency.

What is the reason forthe low power generation of the inverter?

There are various reasons, for which you can find troubleshooting information from the following links:

(1) Check whether the PV panel and inverter match properly.

(2) Check whether the PV panel and inverter normally run, whether there is shadow shielding, and whether each component is wired firmly.
