Is a 4kw off the grid solar system worth it？

4kw grid-connected solar photovoltaic power generation home system introduction

Features of 4kw off the grid solar system:
System composition: photovoltaic panels, solar inverters, fixed brackets, two-way electricity meters (provided free of charge by the grid), cables (users configure themselves according to their actual installation conditions);

Scope of application: residential, sun room, garage roof sunshine surface, agricultural and industrial building facilities roof sunshine surface;

Use characteristics: no noise, no pollution, no influence on the home voltage environment, and a certain shading and heat insulation effect;

Energy-saving features: it can be used by itself during the day, and the surplus power is recovered by the power grid;

Maintenance features: Modular design of grid-connected rooftop solar power plant system, no wearing parts, simple maintenance, no worries.

8 application fields of the solar power generation system

Household solar power generation systems are generally composed of photovoltaic arrays composed of solar cell components, solar charge, and discharge controllers, battery packs, off-grid inverters, DC loads, and AC loads. If the output power is AC 220V or 110V, an inverter is also required. The photovoltaic array converts solar energy into electrical energy under the condition of illumination, supplies power to the load through the solar charge and discharge controller, and charges the battery pack at the same time; when there is no light, the battery pack supplies power to the DC load through the solar charge and discharge controller. At the same time, the battery also needs to directly supply power to the independent inverter, which is converted into alternating current through the independent inverter to supply power to the alternating current load.

Choose the right solar off grid power generation system under 4 conditions

Off grid solar power generation systems are widely used in remote mountainous areas, non-electric areas, islands, communication base stations and other applications. The system is generally composed of photovoltaic arrays composed of solar cell components, solar charge and discharge controllers, battery packs, off grid inverters, DC loads and AC loads. The photovoltaic array converts solar energy into electrical energy under the condition of illumination, and supplies power to the load through the solar charge and discharge controller, and charges the battery pack at the same time; when there is no illumination, the battery pack supplies power to the DC load through the solar controller, while the battery pack It is also necessary to directly supply power to the independent inverter, convert it into AC power through the independent inverter, and supply power to the AC load.
