Building your own electricity generation off the grid is an attractive idea – freedom, self-sufficiency and connection to nature. But many people are surprised by the amount of detail and technical choices required to make a successful system. So what are the most common challenges to be aware of when procuring a renewable energy electricity system? <\/strong><\/p>\n Solar panels are an excellent means of generating electricity, but the energy they produce varies greatly depending on the weather and the seasons:<\/p>\n Cloudiness, shadows on branches and short days reduce yields significantly.<\/p>\n<\/li>\n From November to February, the yield in Finland is very low – which is why an aggregate is often an essential backup system.<\/p>\n<\/li>\n<\/ul>\n Wattium’s energy-efficient solution requires fewer panels, allowing you to save wood around the cottage and reduce fuel consumption in the winter season.<\/p>\n The battery stores energy for use when the sun is not shining. Herein lies the biggest challenge for many off-grid systems: <\/p>\n Lead-acid batteries wear out quickly and cannot tolerate deep discharges.<\/p>\n<\/li>\n AGM and gel batteries offer an improvement, but even they have a limited lifetime.<\/p>\n<\/li>\n Lithium iron phosphate (LiFePO\u2084) batteries are superior in terms of durability, capacity and safety.<\/p>\n<\/li>\n<\/ul>\n Wattium uses a special LiFePO\u2084 battery that can be charged even at temperatures below 0\u00b0C – a crucial advantage in Finnish conditions.<\/p>\n The inverter converts the direct current from the batteries into 230V alternating current suitable for home appliances. Here again, quality and technology are key: <\/p>\n Modified sine wave is not suitable for sensitive devices.<\/p>\n<\/li>\n High-Frequency inverters can limit power, especially during start-up peaks.<\/p>\n<\/li>\n Low-Frequency inverters provide a reliable, clean sine wave and can withstand demanding applications.<\/p>\n<\/li>\n<\/ul>\n The Wattium combines high output power with low self-consumption, allowing you to run several high-powered devices simultaneously without worrying about battery drain.<\/p>\n Self-built systems require careful planning and installation skills. An incorrectly constructed electrical system can create a fire hazard or damage equipment. <\/p>\n The Wattium is pre-assembled and encased, ensuring fire and electrical safety and a neat appearance – ready to use.<\/p>\n Energy management is an essential part of off-grid life. Many systems offer applications, but they can be technical and complex to use. <\/p>\n Wattium’s user interface has been developed with the user in mind: energy consumption, charging status and settings are displayed at a glance in the mobile app. Important functions such as setting the sleep mode are also easy to perform. <\/p>\n Since solar is not always enough, an aggregate is an important part of a reliable system. The important thing is to choose: <\/p>\n An inverter-aggregator that produces high quality electricity and is quiet.<\/p>\n<\/li>\n Remote start, allowing automatic or mobile control of the aggregate.<\/p>\n<\/li>\n<\/ul>\n Wattium recommends a carefully selected, high-quality model that works seamlessly with the system and minimizes fuel consumption.<\/p>\n The purchase of a renewable energy system involves many important choices: panels, batteries, inverters, commissioning and monitoring. Once these things are done right, you can enjoy truly worry-free and sustainable electricity – all year round, whatever the weather. <\/p>\n Wattium is designed for just that: a simple, safe and reliable solution<\/strong> that takes the convenience of everyday life where the grid doesn’t reach.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ admin_label=”Blogiosio EN” _builder_version=”4.27.4″ _module_preset=”default” global_module=”3580″ saved_tabs=”all” global_colors_info=”{}”][et_pb_row _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_blog fullwidth=”off” posts_number=”3″ include_categories=”44″ show_more=”on” show_author=”off” show_date=”off” show_categories=”off” module_class=”et-custom-read-more-text” _builder_version=”4.27.4″ _module_preset=”default” border_radii=”off|10px|10px||” border_radii_image=”off|10px|10px||” global_colors_info=”{}”][\/et_pb_blog][et_pb_code _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”]Variation in solar panel output<\/h2>\n
