It monitors the modules, communicates with the inverter and provides the bottom support. It contains no battery cells and stores no energy. A working tower requires two to five separately purchased matching Reserva modules, a compatible Fronius hybrid inverter, project protection, cabling and professional commissioning.<\/p>\n<h2>Exact sold assembly<\/h2>\n<ul>\n<li>Sold item: 1 \u00d7 Fronius Reserva BMS with base, article 4,240,371<\/li>\n<li>Compatible tower size: 2\u20135 matching Reserva modules<\/li>\n<li>System usable energy after adding modules: 6.31\u201315.79 kWh<\/li>\n<li>BMS: 330 \u00d7 772 \u00d7 176 mm, 16 kg<\/li>\n<li>Base: 60 \u00d7 772 \u00d7 176 mm, 3.5 kg<\/li>\n<li>Installed BMS\/base assembly: 390 \u00d7 772 \u00d7 176 mm, 19.5 kg<\/li>\n<li>Shipping package: 790 \u00d7 554 \u00d7 315 mm, 25 kg<\/li>\n<li>Complete correctly assembled system: IP65, \u221220 to +55 \u00b0C, indoor or protected outdoor installation<\/li>\n<\/ul>\n<h2>Battery management and compatibility<\/h2>\n<p>The BMS calculates state of charge, monitors overvoltage, undervoltage, overcurrent, temperature and cell or hardware faults, provides dark-start support, exchanges operating data over RS485 and receives battery firmware updates through the inverter interface. The current Fronius compatibility table covers suitable Primo GEN24 Plus, Symo GEN24 Plus and Verto Plus variants; Fronius Symo Hybrid is excluded. Up to four equal-capacity towers may be operated in parallel, subject to the current design rules.<\/p>\n<h2>Official package contents<\/h2>\n<p>The European package contains the top, left and right covers, BMS, quick-start guide, drilling template, two RJ45 plugs, two RJ45 screw connections for parallel operation, one LP-16-C\/RJ45 plug for the inverter connection, two pairs of St\u00e4ubli MC4-Evo stor 6 mm\u00b2 connectors, three M6\u00d712 TX30 screws, two base-plate covers and the base plate. The 10 mm\u00b2 connectors shown in the international instructions are supplied only in Australia and New Zealand and are not part of this European package.<\/p>\n<h2>Project limits and installation<\/h2>\n<p>Battery modules, inverter, backup switching, meter, external protection, project cables, wall and floor preparation, installation and commissioning are separate. This is high-voltage equipment for qualified installation. The supporting structure, clearances, cable routing, inverter firmware and exact permitted configuration must be checked against the current Fronius documentation before assembly. The system warranty is stated by Fronius for ten years; the current applicable terms and the exact sealed article are confirmed before dispatch.<\/p>\n<p><a href=\"https:\/\/wodatherm.com\/wp-content\/uploads\/2026\/09\/fronius-reserva-official-datasheet-en-v08-2025.pdf\">Download the locally hosted official English Reserva datasheet<\/a> and <a href=\"https:\/\/wodatherm.com\/wp-content\/uploads\/2026\/09\/fronius-reserva-official-operating-instructions-en.pdf\">operating instructions<\/a>.
