On-Grid Inverter<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The on-grid inverter is the most common type and is suitable for solar power systems directly connected to the national grid. This type of inverter does not require an energy storage system and is ideal for those who use more electricity during the day. Currently, on-grid inverters are divided into three types: micro inverters, string inverters, and central inverters.<\/p>\n<p><strong>Advantages:<\/strong><\/p>\n<ul>\n<li><strong>Cost-effective:<\/strong> On-grid inverters are less expensive than other types of inverters, helping to reduce initial investment costs.<\/li>\n<li><strong>High durability:<\/strong> On-grid inverters have a simple design, are durable, and require minimal maintenance.<\/li>\n<li><strong>Performance optimization:<\/strong> Without an energy storage system, on-grid inverters directly use electricity from the solar panels to supply electrical devices.<\/li>\n<\/ul>\n<p><strong>Disadvantages:<\/strong><\/p>\n<p>When there is a power outage, systems using on-grid inverters will not operate. This is a significant drawback if you live in an area with frequent power outages.<\/p>\n<p>Reputable brands on the market offering on-grid inverters: Growatt, Goodwe, Sungrow.<\/p>\n<figure id=\"attachment_7939\" aria-describedby=\"caption-attachment-7939\" style=\"width: 800px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-7939 size-full\" src=\"https:\/\/sntek.vn\/wp-content\/uploads\/2024\/12\/bien-tan-hoa-luoi-ongrid.jpg\" alt=\"Bi\u1ebfn t\u1ea7n n\u0103ng l\u01b0\u1ee3ng m\u1eb7t tr\u1eddi ho\u00e0 l\u01b0\u1edbi\" width=\"800\" height=\"450\" srcset=\"https:\/\/sntek.vn\/wp-content\/uploads\/2024\/12\/bien-tan-hoa-luoi-ongrid.jpg 800w, https:\/\/sntek.vn\/wp-content\/uploads\/2024\/12\/bien-tan-hoa-luoi-ongrid-300x169.jpg 300w, https:\/\/sntek.vn\/wp-content\/uploads\/2024\/12\/bien-tan-hoa-luoi-ongrid-768x432.jpg 768w, https:\/\/sntek.vn\/wp-content\/uploads\/2024\/12\/bien-tan-hoa-luoi-ongrid-470x264.jpg 470w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-7939\" class=\"wp-caption-text\">On-Grid Solar Inverter<\/figcaption><\/figure>\n<h3><span class=\"ez-toc-section\" id=\"2_Off-Grid_Inverter\"><\/span><strong>2.
