Off grid solar system is more complex in installation than on grid solar system, as it requires more components like charge controller and batteries, so it needs higher technical skills and costs more. Although of this, off grid solar system market grows and most of suppliers / manufacturers try to save the cost and complexity by searching and implements new techniques and services that you should pay attention for as following.
Off grid solar inverter converts DC electricity comes from solar panels and stored in Batteries to AC electricity to be used to run all of AC loads types existing now like TV, refrigerator, oven, lights, air conditions…etc. What are parameters to check when buying the off-grid inverter?
Invreter.com online store provides two kinds of off grid solar inverters: Multi-function inverter/ charger with rated power 700W to 6000W and three phase pure sine wave inverter with high power 8kW to 200kW. Cheak the price list as shown below and choose the right off grid inverter to meet your PV system.
The off-grid photovoltaic power generation system for household use consists of the photovoltaic module, supporter, controller, solar inverter, accumulator and power distribution system. The system's electric plan design should take the selection and computing of modules, inverters (controllers), and accumulators into consideration. Before the plan design, necessary preparation should be made, because the off-grid is customized without a unified plan. Therefore, the user load type and power, electricity consumption in the daytime and in the evening, and climate conditions of the installation place should be first learned. The power supply for the off-grid photovoltaic system relies on the weather, which is not 100% reliable.
In the photovoltaic off-grid system, the power parameter of the power inverter selecting is generally confirmed according to the load type and power of the user. The load is classified into the following types according to the impedance property: Resistive load, inductive load, and capacitive load. The load is classified into the following types according to the impedance property: Resistive load, inductive load, and capacitive load. The resistive load: The load with no phase difference between current and voltage is a resistive load, such as the electric cooker, bulb, electric furnace, electric soldering iron and so on.
