Zendure has built a solid reputation in the niche market of balcony solar kits—systems that allow individuals to install small solar panels on their balconies or rooftops to reduce their electricity bills. These systems typically involve connecting a couple of solar panels, but a common drawback is that any excess energy produced during the day is sent back to the grid without providing a financial return. The new Zendure SolarFlow 800 Plus aims to solve this issue with an integrated lithium iron phosphate (LFP) battery that stores energy for use during the evening or when solar production drops. This system is currently being sold on Amazon at a 14% discount, bringing its price down from 539 euros to 462.13 euros, but the offer is only valid for today. The core of the system is a 1920 Wh LFP battery, known for its long lifespan and stability. This battery stores surplus energy generated during the day and releases it when solar panels are not producing, such as during the evening or on cloudy days. If the base capacity proves insufficient, users can expand the system by adding more battery modules, allowing for future upgrades as energy needs grow. The system also includes an 800 W inverter and two MPPT (Maximum Power Point Tracking) inputs capable of handling up to 1500 W of solar power, ensuring efficient energy capture even under less-than-ideal conditions. The intelligent aspect of the system is managed by the ZENKI home manager, which monitors weather conditions, user habits, and dynamic electricity prices to optimize when the battery charges and discharges. According to Zendure, this can lead to up to 42% savings on electricity bills, although this number is theoretical and depends heavily on individual usage patterns and local energy prices. The system is compatible with popular smart home platforms like Linky (TIC), Shelly, and HomeWizard, making it easier for users to track and manage their energy consumption. Installation is designed to be simple and quick, with a "Plug and Play" setup that requires no additional wiring or installation costs. The inverter adjusts its output from 0 to 800 W in under three seconds, ensuring it closely matches the user's energy needs and minimizing reliance on the grid. The IP65 certification allows the system to be installed outdoors, though users should be aware that feeding energy back into the grid may be subject to local regulations. For those considering similar systems, a comparison guide is available to help choose the best plug-and-play solar battery for their needs.
