BAE Secura PVV Gel Block - Solar Batteries
BAE Secura PVV block Gel batteries are compact and powerful valve regulated lead acid (VRLA) batteries - perfect for solar power systems. They are used in grid-interactive as well as in off-grid solar systems. Made by BAE Batterien GmbH in Germany, and available in 287 to 431 Amp Hour capacity.
We sell the Secura PVV Solar Block range from BAE. The Secura PVV Solar is a Gel type battery that comes in 2 x 6 volt blocks. All prices for BAE batteries on our website (as with all our batteries) are for 12 volt sets. The interconnecting straps are included in the price.
BAE solar batteries are rated ~7500 cycles @ 20% Depth of Discharge (meaning your battery remains 80% full). Due to the high cycle life requirements tubular plates are used. They are made for indoor use.
No Maintenance
Gel batteries do not require top ups, the only maintenance that should be performed is:
- Voltage and temperature check (every 6 months)
- Battery connection check (every 12 months)
