New Energy Relay - PV Relay Series

Pulished on Sep. 22, 2020

Relay manufacturers have been increasing their investment in the photovoltaic (PV) system market. In particular, Japanese relay manufacturers have been actively pursuing the development of new products and expanding relay models with small size, large capacity and low power consumption for use in PV equipment They have also been investing funds in increasing production and improving marketing systems to meet the expansion of demand in Japan and abroad. At the same time, the success of solar equipment promotes the production of relays. With the development of solar equipment, The IVY brand of relays also saw many opportunities to support the new infrastructure.


Because solar panels convert light energy (note that it’s light energy, not heat) to power the battery, as we all know, the intensity of sunlight is different every hour, morning and evening weak, and strong at noon, so the solar panel cannot It has a stable voltage supply like a mobile phone charger. Is there no way then? Of course there is a way, which is called a relay device. In order to achieve a stable power supply, IVY provides relays that can be applied to solar cells (solar panels), power conditioners, storage batteries and other products.


The essence of a relay is a switch controlled by an electromagnetic coil. Simply put, it is an electrically controlled switch. In the electrical control system, it has the functions of receiving, holding, flipping, multiplying, delaying, isolating and amplifying the input signal. It is a traditional classic control component. There are many kinds of relays now, mainly divided into three types: low power, medium power and high power. Basically, low-power controllers are used in lighting systems. The main function of this controller is to balance the functions of various components and optimize the efficiency of the entire system. In photovoltaic lighting, another function of the relay is to protect the battery from overcharging and overdischarging. In places with large temperature differences, a qualified controller should also have the function of temperature compensation. Other additional functions such as light-controlled switches and time-controlled switches should be optional relays.


The relay department recently launched an innovative small-size power relay for use in photovoltaic inverters in modern photovoltaic power generation systems. The power relay can smoothly transmit solar energy to the grid. In an emergency, these devices will cut off the connection between the photovoltaic power generation system and the national grid in accordance with today's safety regulations.


The power relay is characterized by a low holding power of only 200mW, a coil power of 1.5W, a contact gap of 1.5mm and a rated current of 32/64/80/90A. Its operating temperature range is -25 to 75 degrees Celsius and is fully RoHS compliant. As above, you can use IVY brand IM601 and IM901 relay models.
