Surplus generation can stay in the home rather than being exported. The controller distinguishes solar production from stored battery energy to avoid unnecessary battery discharge.\n\nWhen generation is insufficient, heating can use grid electricity. A&nbsp;spot tariff allows scheduling during cheaper hours, but is not required to use solar surplus. Results depend on generation, hot-water demand and system settings. <h2>Choose the appropriate variant and settings<\/h2>\nThe application 1.5 release describes 1F and 3F variants. The three-phase solution requires installation by an electrician. Features depend on the device and system configuration, so confirm inverter connectivity and water-heater suitability before ordering.\n\nThe application provides temperature, tank-volume and heating-element settings, plus heating-status monitoring. Manual heating can start without waiting for favourable conditions. <a style=\"color: #090446; text-decoration: underline;\" href=\"\/en\/control-heat-en\/\">Explore Guardexy Heat<\/a><a style=\"color: #090446; text-decoration: underline;\" href=\"\/en\/contact\/?tema=reseni&amp;pro_koho=domaci-fve\">Discuss a&nbsp;suitable solution<\/a>\n<span class=\"gx-article-related\"><strong>Related reading<\/strong><a href=\"\/en\/what-to-monitor-in-solar-operation\/\">What to monitor in solar operation <span aria-hidden=\"true\">\u2192<\/span><\/a><a href=\"\/en\/how-to-prepare-secure-remote-access-to-solar-installations\/\">How to prepare secure remote access to solar installations <span aria-hidden=\"true\">\u2192<\/span><\/a><\/span> \t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e610314 elementor-widget elementor-widget-heading\" data-id=\"e610314\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<p class=\"elementor-heading-title elementor-size-default\"><span class=\"gx-article-meta\"><a href=\"\/en\/news\/\">\u2190 Back to News<\/a><span>GUIDE \u00b7 CONTROL<\/span><time datetime=\"2026-09-23\">2026-09-23<\/time><\/span><\/p>\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/main>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Ways to use available energy in batteries, consumption and water heating.<\/p>\n","protected":false},"author":7,"featured_media":12500,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"elementor_header_footer","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[44,42],"tags":[45],"class_list":["post-2709","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-guide","category-news","tag-control-en"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.guardexy.eu\/en\/wp-json\/wp\/v2\/posts\/2709","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.guardexy.eu\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.guardexy.eu\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.guardexy.eu\/en\/wp-json\/wp\/v2\/users\/7"}],"replies":[{"embeddable":true,"href":"https:\/\/www.guardexy.eu\/en\/wp-json\/wp\/v2\/comments?post=2709"}],"version-history":[{"count":0,"href":"https:\/\/www.guardexy.eu\/en\/wp-json\/wp\/v2\/posts\/2709\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.guardexy.eu\/en\/wp-json\/wp\/v2\/media\/12500"}],"wp:attachment":[{"href":"https:\/\/www.guardexy.eu\/en\/wp-json\/wp\/v2\/media?parent=2709"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.guardexy.eu\/en\/wp-json\/wp\/v2\/categories?post=2709"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.guardexy.eu\/en\/wp-json\/wp\/v2\/tags?post=2709"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
