In you are seeking a stand-alone system, the capacity to store power is necessary. At this present time the only viable option is a battery bank. At the Wind and Solar Shop we use the Yuasa NPL Series Valve Regulated Lead-Acid Batteries (VRLA).
These batteries differ from normal lead-acid batteries as they are sealed. This design prevents the spillage of gases and acid, making them more friendly to both the user and the environment. The NPL range is an enhanced NP design resulting in a longer service life (7 - 10yrs). All other attributes and operational characteristics are the same, thereby maintaining the benefit of a common mechanical and electrical design.
Features
• Yuasa VRLA batteries can be used in any orientation excluding continuous use inverted.• Standard case material is flame retardant to (UL94) HBØ.
• FR option case material is flame retardant to UL94:VØ (oxygen index 30).
• NPL batteries are manufactured in factories that comply with ISO 9001:2000.
• FR option NPLs comply with BS6290 Part 4 (1997).
• NPL batteries comply with IEC 60896-21+22.
