It is not a complete battery tower and cannot operate alone. A working system requires two to five matching modules, the separately selected Reserva BMS\/base, a compatible Fronius hybrid inverter, protection, project cabling and professional commissioning.<\/p>\n<h2>Exact module data<\/h2>\n<ul>\n<li>Sold item: 1 \u00d7 Fronius Reserva Module, article 4,240,370<\/li>\n<li>Usable energy: 3.15 kWh<\/li>\n<li>Rated voltage: 102.4 V DC<\/li>\n<li>Cell chemistry: lithium iron phosphate (LFP), pouch cells<\/li>\n<li>Dimensions: 250 \u00d7 772 \u00d7 176 mm (H \u00d7 W \u00d7 D)<\/li>\n<li>Module weight: 33.5 kg; packaged module 36.5 kg<\/li>\n<li>Complete correctly assembled system: IP65, \u221220 to +55 \u00b0C, indoor or protected outdoor installation<\/li>\n<\/ul>\n<h2>Reserva system configuration<\/h2>\n<p>Two, three, four or five identical modules form Reserva 6.3, 9.5, 12.6 or 15.8 with 6.31\u201315.79 kWh usable energy. 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. The maximum battery output current remains 32 A for the complete parallel group, so additional towers increase energy capacity but do not multiply that current limit.<\/p>\n<h2>Included parts and project exclusions<\/h2>\n<p>The official module package contains one battery module, two covers, two L-shaped mounting brackets, four M6\u00d712 TX30 screws, two M6 washers and a quick-start guide. Reserva BMS\/base, additional modules, inverter, backup switching, metering, external protection, cables, wall\/floor preparation, installation and commissioning are separate.<\/p>\n<h2>Safety and service-life basis<\/h2>\n<p>This is high-voltage equipment for qualified installation. The 33.5 kg module needs planned handling and a verified supporting structure. Fronius states a ten-year system warranty and an expected 6,000-cycle reference to 60% state of health under the datasheet test conditions; actual life and available power depend on temperature, current, depth of discharge, inverter and operating profile. Exact label, generation, firmware, compatible inverter and current warranty terms 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>.
