Thanks to its modular design and safe LiFePO\u2084 chemistry, it delivers stable power, high performance, and full adaptability to user needs.<\/p>\n<p data-start=\"475\" data-end=\"641\">The system is ideal for off-grid or hybrid energy systems, helping reduce dependence on the power grid and optimize electricity costs.<\/p>\n<p data-start=\"695\" data-end=\"926\">The modular architecture makes it easy to scale the system according to consumption. The 20 kWh configuration provides an optimal balance between capacity and efficiency, and if needed, it can be expanded to a much larger capacity.<\/p>\n<p data-start=\"928\" data-end=\"1088\">This solution is especially relevant for those planning to build or upgrade a solar power plant who want to get the maximum return from the energy produced.<\/p>\n<p data-start=\"1125\" data-end=\"1269\">The system is built on lithium iron phosphate (LiFePO\u2084) technology, known for its high thermal stability and long service life. It:<\/p>\n<ul data-start=\"1270\" data-end=\"1357\">\n<li data-section-id=\"qk5ioc\" data-start=\"1270\" data-end=\"1293\">contains no cobalt<\/li>\n<li data-section-id=\"eq7pn3\" data-start=\"1294\" data-end=\"1317\">resists overheating<\/li>\n<li data-section-id=\"xhy57x\" data-start=\"1318\" data-end=\"1357\">delivers thousands of charge cycles<\/li>\n<\/ul>\n<p data-start=\"1359\" data-end=\"1495\">The intelligent management system (BMS) continuously monitors the battery&#8217;s condition, protecting it from overvoltage, overloads, and short circuits.<\/p>\n<p data-start=\"1537\" data-end=\"1729\">The system has an IP65 protection rating and operates reliably over a wide temperature range, from -20\u00b0C to +55\u00b0C. Passive cooling reduces component wear and improves overall reliability.<\/p>\n<p data-start=\"1731\" data-end=\"1819\">This allows the battery to be used both indoors and in outdoor installations.<\/p>\n<p data-start=\"1866\" data-end=\"2102\">The Deye AI-W5.1-B supports combining a large number of modules into a single system. This makes it possible to build energy storage with a capacity of up to 184 kWh, suitable for private homes as well as businesses and industrial facilities.<\/p>\n<p data-start=\"2145\" data-end=\"2200\">The system is designed for ease of operation:<\/p>\n<ul data-start=\"2201\" data-end=\"2314\">\n<li data-section-id=\"125ni22\" data-start=\"2201\" data-end=\"2236\">automatic module connection<\/li>\n<li data-section-id=\"1oe4i70\" data-start=\"2237\" data-end=\"2264\">remote monitoring<\/li>\n<li data-section-id=\"1ktg2y1\" data-start=\"2265\" data-end=\"2314\">software update capability<\/li>\n<\/ul>\n<p data-start=\"2316\" data-end=\"2428\">The compact design allows the battery to be installed on the floor or on a wall without complicated installation work.<\/p>\n<p data-start=\"2449\" data-end=\"2702\">The Deye AI-W5.1-B 20 kWh is a versatile solution for those seeking energy independence and stability. It combines safety, scalability, and modern technology, enabling efficient energy storage and use in any conditions.<\/p>\n","protected":false},"excerpt":{"rendered":"<table id=\"product-attribute-specs-table\" class=\"data table additional-attributes\">\n<caption class=\"table-caption\">\u00a0<\/caption>\n<tbody>\n<tr>\n<th class=\"col label\" scope=\"row\">Brand<\/th>\n<td class=\"col data\" data-th=\"Brand\">Deye<\/td>\n<\/tr>\n<tr>\n<th class=\"col label\" scope=\"row\">Dimensions<\/th>\n<td class=\"col data\" data-th=\"Dimensions\">720\u0445255\u04451412<\/td>\n<\/tr>\n<tr>\n<th class=\"col label\" scope=\"row\">Number of modules<\/th>\n<td class=\"col data\" data-th=\"Number of modules\">4<\/td>\n<\/tr>\n<tr>\n<th class=\"col label\" scope=\"row\">Nominal voltage<\/th>\n<td class=\"col data\" data-th=\"Nominal voltage\">51.2 V<\/td>\n<\/tr>\n<tr>\n<th class=\"col label\" scope=\"row\">Energy consumption<\/th>\n<td class=\"col data\" data-th=\"Power consumption\">18.4 kWh<\/td>\n<\/tr>\n<tr>\n<th class=\"col label\" scope=\"row\">Charge\/discharge current<\/th>\n<td class=\"col data\" data-th=\"Charge\/discharge current\">200-360 A<\/td>\n<\/tr>\n<tr>\n<th class=\"col label\" scope=\"row\">Protection rating<\/th>\n<td class=\"col data\" data-th=\"Ingress protection rating\">IP65<\/td>\n<\/tr>\n<tr>\n<th class=\"col label\" scope=\"row\">Output voltage, V<\/th>\n<td class=\"col data\" data-th=\"Output voltage, V\">51.2 V<\/td>\n<\/tr>\n<tr>\n<th class=\"col label\" scope=\"row\">HV\/LV<\/th>\n<td class=\"col data\" data-th=\"HV\/LV\">Low-voltage<\/td>\n<\/tr>\n<tr>\n<th class=\"col label\" scope=\"row\">Battery type<\/th>\n<td class=\"col data\" data-th=\"Battery type\">Lithium iron phosphate<\/td>\n<\/tr>\n<tr>\n<th class=\"col label\" scope=\"row\">Number of cycles<\/th>\n<td class=\"col data\" data-th=\"Cycle life\">6000<\/td>\n<\/tr>\n<tr>\n<th class=\"col label\" scope=\"row\">Capacity, Ah<\/th>\n<td class=\"col data\" data-th=\"Capacity, Ah\">400<\/td>\n<\/tr>\n<tr>\n<th class=\"col label\" scope=\"row\">Capacity (kWh)<\/th>\n<td class=\"col data\" data-th=\"Capacity (kWh)\">20<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":2079,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[60],"product_cat":[48],"product_tag":[],"class_list":["post-2076","product","type-product","status-publish","has-post-thumbnail","product_brand-deye","product_cat-accumulator-batteries","first","outofstock","taxable","shipping-taxable","purchasable","product-type-simple"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.8 -
