WodaTherm\u2122 BDTN LV48<\/strong> is an outdoor low-voltage battery storage system for commercial and larger residential solar PV projects. The verified order specification uses three 51.2 V, 314 Ah battery units in the 48 kWh class, a 0.5C operating reference, an IP54 outdoor cabinet, more than 8,000 cycles under the prescribed conditions, a five-year warranty reference and CE, UN38.3 and MSDS documentation for the ordered configuration.<\/p>\n

The LV48 is the DC battery-storage portion of the project. A compatible low-voltage hybrid inverter or PCS, EMS, backup switching, metering, electrical protection, cabling, foundation, unloading, installation and commissioning are included only when listed in the final WodaTherm\u2122 proposal. The inverter is not automatically included with this catalogue item.<\/p>\n

48 kWh outdoor battery storage for commercial solar PV<\/h2>\n

The LV48 is intended for workshops, farms, offices, retail premises, small production sites, charging locations and homes with a substantial solar and consumption profile. Depending on the approved inverter and electrical design, it can increase on-site use of PV generation, shift energy into evening or night operation, manage selected load peaks or supply project-defined backup circuits. Nominal and usable energy are different values; usable capacity depends on the agreed operating window, reserve strategy and inverter settings.<\/p>\n

10 reasons to place the LV48 battery and inverter outside<\/h2>\n

With a compatible outdoor-rated low-voltage inverter or PCS, the LV48 can form an independent energy point outside the occupied or production building:<\/p>\n

    \n
  1. Preserves valuable indoor floor area:<\/strong> the three-unit battery configuration does not occupy a plant room, workshop, garage, warehouse or retail back room.<\/li>\n
  2. Creates a separate outdoor energy centre:<\/strong> battery, suitable inverter, controls and project protection can be coordinated in one defined technical zone.<\/li>\n
  3. Separates the equipment from people and stock:<\/strong> a fault in the battery or inverter is not located in offices, customer areas, production rooms or stored-goods zones.<\/li>\n
  4. Allows siting near the commercial connection point:<\/strong> the unit can be planned near the PV distribution, main switchboard, workshop, farm building or local charging infrastructure.<\/li>\n
  5. Provides direct maintenance access:<\/strong> inspection and service can take place without moving technicians through a home, controlled production area or customer-facing space.<\/li>\n
  6. Keeps rejected heat and fan noise outside:<\/strong> cooling heat and operating sound do not add to occupied or temperature-controlled rooms.<\/li>\n
  7. Supports a short high-current 51.2 V DC path:<\/strong> locating the compatible inverter beside the cabinet helps limit cable length, voltage drop and losses at the substantial currents of a 48 kWh low-voltage system.<\/li>\n
  8. Simplifies handling of the three-unit configuration:<\/strong> an accessible outdoor position makes delivery, cabinet access and later module work easier to plan.<\/li>\n
  9. Enables a dedicated security perimeter:<\/strong> anchoring, locks, fencing, bollards, lighting, CCTV and controlled access can protect battery and inverter together.<\/li>\n
  10. Supports future site development:<\/strong> the outdoor plan can reserve service space or a route for later energy equipment when the approved design permits expansion.<\/li>\n<\/ol>\n

    51.2 V architecture and inverter compatibility<\/h2>\n

    Three 51.2 V, 314 Ah battery units provide a calculated nominal energy of approximately 48.2 kWh. At the quoted 0.5C reference, the corresponding battery-side power is approximately 24.1 kW. This is an engineering reference, not guaranteed AC output. Actual charge and discharge power, backup operation and grid functions depend on the approved inverter or PCS, its current limit, operating window, BMS protocol and the complete system design.<\/p>\n

    A low-voltage system carries high DC current. Cable cross-section and length, busbars, fusing, isolation, connectors, protection and terminal torque must be engineered together. Matching 51.2 V alone is insufficient; WodaTherm\u2122 verifies inverter current capability and communication compatibility with the supplied BMS before production.<\/p>\n

    IP54 cabinet with active heating and cooling<\/h2>\n

    IP54 limits dust ingress and protects against splashing water within the relevant test conditions; it is not an immersion or flood rating. The site requires a level load-bearing base, drainage, protected cable entries, service clearances, ventilation, earthing, vehicle-impact protection and controlled access. Uncontrolled roof runoff, flood paths and locations where snow or stored material can block airflow must be avoided.<\/p>\n

    Active heating and cooling support seasonal outdoor operation under BMS supervision. Final thermal setpoints, auxiliary consumption, condensate routing and the permitted ambient range are confirmed for the site’s climate, solar exposure, altitude and duty cycle.<\/p>\n
