independent electric power supply systems engineering design and installation training guide
Provide independent power systems design and independent electric power systems installation solutions, and talk about photovoltaic modules, inverters and system maintenance in power systems engineering
Talk about the inverters for independent power supply systems, including the safety of independent system components, site safety and safety equipment, etc.
Inverters generally have multiple protection circuits. 1. Reverse polarity protectionReverse polarity protection prevents improper connection to the battery, albeit at the cost of reduced efficiency, but is still valuable for mobile applications. It should be noted that not all inverters have reverse polarity protection. 2. Overload protectionThe most important thing for overload protection is to […]
There are mainly two different criteria for distinguishing the types of inverters. 1. The way of converting direct current to alternating current1) Rotary inverters (motor inverters) Before the advent of solid-state inverters, 240V alternators driven by DC motors were widely used to convert between DC and AC. This conversion method benefits from the mechanical inertia […]
Of further concern in AC systems are the reactive elements (inductive and capacitive elements in sinusoidal AC circuits). Reactance can be either capacitive or inductive, but no work is done by current flowing through either type of reactance. The electrical power in a DC circuit is equal to the product of the voltage and the […]
Loads composed of purely resistive elements (resistive loads) can be powered by DC, so there is no need to use an inverter. However, due to the large power consumption of resistive loads, the use of such loads should be limited in independent power supply systems, including electric heaters, kettles, water heaters, electric irons, and hair […]
