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 harger such as POW-LVM5K-48V-H 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.
