With well over 4 million products sold in over 100 countries since 1993—functioning in some of the most extreme environments and mission-critical applications in the world—Morningstar Corporation can truly claim to be “the leading supplier of solar controllers and inverters.” That success is why Morningstar has had staying power and stable management for over 27 years, along with the lowest employee turnover rate— in an industry where many companies come and go.

 

Morningstar’s main advantage can be summed up in two words: employee ownership. Our own reputations literally ship with each product we make, so we continually strive to keep our quality and reliability at an industry-record high. This is how we’ve earned the lowest hardware failure rate in the industry. Employee ownership is the secret behind our industry-leading quality and value—and why those words are not just a cliché or catch-phrase, but actually mean something at Morningstar.

 

Morningstar has over 20 patents and a dozen trademarks associated with thermal engineering, mechanical design, charging and control, advanced electronic topologies, safety systems, and more. We invest in the best R&D talent and resources available, with a ratio of designers and engineers unparalleled in our segment of the renewables industry. We maintain 35kW of photo-voltaic solar at our facility for real-world testing, research, and evaluation.

 

 

PowMr was established in 2016. We deal in these following prouducts: Batteries; Battery chargers; Connections for electric lines; Converters for electric plugs; Electric cables; Electric cables, wires, conductors and connection fittings therefor; Electric contacts; Electric wires; Electrical connectors; Electrical plugs and sockets; Inverters; Photovoltaic cells; Solar batteries; Solar panels for the production of electricity; Wire connectors.

 

We are a team with 4 years history,aspiring to be the leader of PV industrial. We offer good quality and faith service as the purpose.

 

In previous 4 years, we sold other companies’ products, but customers' demand were not satisfied, so we started our own business In 2013. After analysing customers' different needs, we develop new controllers by cooperating with factories. So far, we have launched 6 different kinds of controllers, such as S series solar charge controller and G series solar charge controller which are very popular after coming to market. For protecting the patent of our products, in year 2016 we registered our brand in America, name as PowMr. We ran our own stores on Amazon in year 2017.

 

 

Most solar power systems include charge controllers for the purpose of protecting storage batteries and avioding battery overcharing. The basic fuction of charge controllers is to rupture the charging current when the storage battery was fully charged. Due to the different features of different kinds of storage batteries, customers are supposed to choose charger controllers according to the kind of battery.

 

 

Those solar power systems which connect to the battery need charger controller. The charger controller is used for adjust battery charging or battery group charging. Without it, battery can not be charged efficiently and may get damaged due to the overcharging or discharging.

 

 

Those solar power systems which are equipped with lithium ion battery need the solar charge controller. This kind of controller is designed to be matched with lithium ion battery. Any appliances, such as RV, yacht, water pump, hybrid car and off-grid facilities that equipped with lithium ion battery all needs this specific solar charger controller. Transmission loss should be avoided wherever the solar charger controller be installed. The transmission line from panel to controller and other transmission line from controller to battery should work efficiently with the least transmission loss. The solar charger controller for lithium ion battery is supposed to be installed near the battery in order to manage as requested.

 

 

The factors are as follows:

 

1、Charging Voltage

The charging voltage must exceed the voltage of battery when it is full-charged. Otherwise, the storage battery can not be full-charged.

 

2、Charging Efficiency of Power System

The higher the charging efficiency, the weaker the internal resistance and the stronger the charging current. Therefore, the charging effect will be better.

 

3、Charging Pattern

The best charging pattern is that charge with constant current first and then charge at constant voltage.
