Need Inverter Charger and solar charge controller when we build our solar system, need these items? The answer is yes. You can get more information including solar pannel, power storage solutions, even on-grid and off-grid when you read the following content.
In whole solar system, inverter charger have 2 basic feature as below:
1.Convert DC power from battery package into AC for household just like FAN, TV, air conditions and so on.
2.Convert AC into DC energy for charging cycle batteries just like lead acid battery and lithium battery. This is core theory about the solar system and applications.
Hybrid inverter charger such as POW-SunSmart 10K allow multiple AC or DC power sources such as generator or grid, solar pannel, to charge the batteries package. You can charge the battery package whenever cloudy, the grid goes down. So the item can provide stable and reliable standby power supply, even main power.
Solar charge controller charge battery package in one direction, charging lead acid battery or lithium batteries from the solar modules and preventing the current from draining back into the PV array at night or cloudy, rainy, snowy.
There are two mainly charging form PWM(Pulse Width Modulation) and MPPT(Maximum Power Point Tracking) now. For example, the HHJ-60 from Hehejin is a MPPT solar charge controller with temperature sensor, LCD screen with muiltiple electronic overcurrent protections. The difference is how to effectively charge batteries from a PV system.
In most cases the MPPT style solar charge controller, such as the HHJ-60A, is the better choice, capturing PV energy far more efficiently and allowing for more flexible configurations of solar panels and batteries package.
Almost all of solar system applications require both inverter charger and solar charge controller. On the one hand, MPPT charge controllers provide optimal charging efficiency, the sunshine may still not be enough to reliably charge batteries in winter or during bad weather or night. Many power loads also require standard AC current. Because of these reasons, inverter charger is required to keep batteries adequately charged and provide power that can be widely used. On the other hand, inverter chargers are not equipped to directly charge batteries from the DC current provided by a PV array. A charge controller is required to appropriately match the PV voltage to the battery and regulate charging.
Of course, there are few exceptions. For example, you maybe only need the solar charge controller feature in a specially PV system. The thing is all of your power loads only accept DC current and your PV array can reliably charge your batteries package.
In on-grid system, because there is no batteries package,and the inveter charger is design for on-grid. In the case, storage or backup systems without batteries, you only need an inverter charger to connect the system.
Is a solar charge controller necessary?
Solar energy is an alternative energy source that relies on solar power generation and is a green and environmentally friendly energy source. A solar charge controller is an essential element of any solar panel system. Most households in tropical and subtropical regions have purchased solar charge controllers, which are almost one of the must-have household appliances. Of course, most households buy PowMr's solar charge controllers.
The sun's rays hit the solar panels, which generate electricity. These powers are direct current and must be converted into alternating current through the inverter, and the alternating current output from the inverter passes through the solar charge controller, and finally enters the battery for storage or power supply for household electrical equipment. A solar charge controller can prevent overcharging the battery and prevent the battery from discharging through the solar panel array at night, making it a great helper at home.
In many ways, a solar charge controller is similar to a battery in that it stores electricity from an inverter and then converts it into a usable form of electricity. Some people believe that using a solar charge controller is unnecessary or even dangerous because if the battery fails and starts to overheat, it can cause a fire or explosion. This kind of thinking is wrong. Every household using a solar photovoltaic system must have a solar controller, so as to protect the battery and electrical equipment.
Using a solar charge controller prevents overcharging and can extend battery life. Failure to use a solar charge controller can cause the battery to overheat and explode, potentially resulting in severe burns and even death for the homeowner and those in the surrounding area. So for the safety of life, please buy PowMr's solar charge controller, the solar controller sold by PowMr is easier and safer to install.
How do I choose a charge controller for my solar system?
Before choosing a charge controller, you must first determine the various parameters of the solar system, and finally, determine which type and size of solar controller to buy. If you don't understand anything, you can directly consult PowMr's customer service online, and we will provide you with professional engineers to answer your questions. Typically, charge controllers are selected for voltages of 12, 24, and 48 volts, and current ratings can range from 1 to 60 amps. This controller is sufficient in many solar photovoltaic systems.
