 Sonnenschein Solar Block Series The Sonnenschein Solar Block Battery range is a very powerful and reliable in rough application conditions. As well as for use in private areas like holiday and weekend houses with more consumer terminals, this range is the ideal energy source for medium industrial solar systems, small solar and wind power stations, offshore buoys, yachts and measuring stations as well as for other safety equipment power supplies. Harness the power of the sun with the Sonnenschein range of dryfit Solar Block Batteries. Built around proven gelled electrolyte technology, Solar Block batteries are simple to use, deep cycling and maintenance free over their complete service life. Maintenance Free and Sealed: Each cell is sealed by a valve preventing penetration by airborne oxygen. Excess pressure (from overcharging is vented and the valve resets. Gas within the battery is recombined to form water. Therefore no water topping up or filling is needed and no acid spill will occur. Mistakes in maintenance are eliminated. Deep Discharge Resistant: Batteries can survive deep discharges and still recover their capacity. Even after 4 weeks left flat the battery can recover to 80% after 48 hours recharging and to 100% after a few cycles. Extremely low Self Discharge: Less than 3% of the rated capacity per month in storage is lost at 20°C. this means batteries can be stored for long periods without recharging. Economical: Excellent performance/price ratio and very low service costs. Up to 6000 cycles according to IEC 896 T2 Storage: Sonnenschein dryfit batteries should only be stored in a fully charged state. After storage batteries should be recharged as follows: Dryfit Solar Block Batteries are designed for applications in various fields: Solar Power Stations, telecommunications systems, traffic light systems, street lighting, alarm systems, weekend and holiday homes, mobile site offices, caravans, ships and maritime buoys. 8 Year Service Life: Designed for 8 year service lifetime at an ambient temperature of 20°C (with 80% residual capacity) Structure and Operation: The Dryfit Solar Block is made up of grid plates of an antimony-free special alloy and separated using high quality micro-porous and specially insulated ‘DARAK’ plastic separators. The individual plates are connected by intercell connectors inside the housing. The plates are installed in easily transportable acid and shock resistant containers made of monoblock polypropylene. Cell Containers and Covers: The cell containers and covers are made of monoblock polypropylene. Container covers are thermally welded to the cell containers to form a permanent and airtight bond. The covers of finished batteries are checked for integrity by a high-voltage test. Electrolyte and Cell Values: Filler plugs are not required. Venting during charging takes place via relief valves that open at a predetermined pressure and close again when the pressure is lowered. Every pressure relief valve is flashback proof and has been tested by UL. The electrolyte used in the dryfit Solar Block range is a special thixotropic gelled type invented by Sonnenschein over 35 years ago. The gel’s properties prevent sedimentation. Handling and Transportation: Sonnenschein dryfit batteries are classified as CLASS 8, UN2880 “Batteries Wet NON-SPILLABLE” For air transportation dryfit batteries are exempt under paragraph 67 of the IMDG Handbook. Plate Block: As there is no shedding of the active material from the plates due to the gel electrolyte, both plate block types rest on the bottom of the container. The solid electrolyte gel provides an additional mechanical fixing. |
