Hoppecke sun power VL 2-1220

Hoppecke sun | power VL 2-1220 — 2V OPzS Tubular Plate Cell Closed (vented) lead-acid cell with tubular plates and liquid electrolyte, developed for heavy cyclic operation in off-grid, hybrid, and peak-shaving applications. The cell withstands prolonged partial charge operation (PSoC) and deep discharge, and achieves a design life of over 20 years with proper charging and 20°C. Key features * Tubular plate positive electrode with polyester sheath, lead-selenium/low-antimony lattice * Up to 1500 cycles at 80% DoD; according to IEC 61427 up to approx. 2400 cycles * Design service life >20 years at 20 °C, >10 years at 30 °C, >5 years at 40 °C * High charging current acceptance, suitable for PSoC operation * Standard prepared for electrolyte circulation (sun | air) * Low self-discharge, insensitive to incidental deep discharge * Dimensions according to DIN 40736-1; manufactured according to EN/IEC 60896-11 and IEC 61427 * Fully recyclable via closed loop Applications * Off-grid and hybrid energy storage (residential, commercial, agricultural) * Peak shaving and voltage stabilization * Village and island power supplies, telecom stations * Pumping systems and cathodic corrosion protection * Long-term emergency power where cycle stability and standby characteristics come together Versions * Filled and charged — ready for immediate commissioning after test charge * Dry pre-charged — for long-term storage or container/air transport; Filling with dilute sulfuric acid, density 1.24 kg/l at 20 °C (higher in cold climate, lower in warm climate). Bank construction and system voltage. Cells are connected in series to the desired system voltage. The cell has two positive and two negative M10 inserts, which allows for parallel strings and low contact resistance. * 12 V bank = 6 cells * 24 V bank = 12 cells * 48 V bank = 24 cells — approx. 58.6 kWh gross (C100), approx. 29 kWh usable at 50% DoD Charging settings (indicative, see manual) Parameter Per cell 24V bank 48V bank Float / trickle charge 2.23 V 26.8 V 53.5 V Absorption / boost 2.40 V 28.8 V 57.6 V Discharge end voltage (>10 h) 1.98 V 23.8 V 47.5 V Discharge end voltage (1 h) 1.81 V 21.7 V 43.4 V * Temperature compensation approx. −4 mV per cell per K above 20 °C — temperature sensor strongly recommended * Recommended charging current 0.1–0.2 × C10 (I10 = 91.5 A); Higher currents are permissible according to the manual * Maximum 80% DoD; fully recharge at least every two weeks to prevent sulfation * Perform equalization charging periodically in accordance with Hoppecke guidelines * A Victron Battery Balancer is not applicable: it balances 12V blocks, not individual 2V cells. Monitoring is performed via midpoint monitoring on the battery monitor. Installation and safety * Closed cell: hydrogen is produced during charging. Ventilate the installation area in accordance with EN IEC 62485-2; never place in a closed cabinet * Acid-resistant substrate, drip tray if locally required * Safety distance to sparking or hot parts (max. surface temperature 300 °C) * Not in direct sunlight or near heat sources; humidity maximum 85% * Optimal operating temperature range 10–30 °C * Dimension series connectors, cell bridges, and battery racks for the maximum discharge current Maintenance * Under normal operation and 20 °C, only top up with demineralized water every 2–3 years * With a recombination system or electrolyte recirculation, top-up intervals increase further * Periodically check and log cell voltages, electrolyte level, and terminal connections Available to order directly * Victron BMV-712 Smart battery monitor — art.
