6 Maintenance
6.1 Battery Maintenance
When main power is unavailable, the battery can support the panel for 24 hours. Sealed lead-acid batteries must be replaced within 3 years from their date of
manufacture. You can get replacement batteries with suitable capacity from the manufacturer. To know the replacement battery capacity, refer the control panel
marking label.
Best practices
• If a battery leaks and contact is made with the Sulphuric Acid, immediately flush skin and eyes with water for at least 15 minutes. Water and household baking soda
provides a good neutralizing solution for Sulphuric Acid.
• Always immediately replace a leaking battery.
• If Sulphuric Acid gets into eyes, seek immediate medical attention.
• Ensure proper handling of the battery to prevent short circuits.
• Take care to avoid accidental shorting of the leads from uninsulated work benches, tools, bracelets, rings, and coins.
• SHORTING THE BATTERY LEADS CAN DAMAGE THE BATTERY AND CAN CAUSE INJURY.
• BATTERIES CONTAIN SULPHURIC ACID WHICH CAN CAUSE SEVERE BURNS TO THE SKIN AND EYES AND DAMAGE TO THE FABRIC.
6.1.1 Maintenance-free batteries
Maintenance-free sealed lead-acid batteries used in the system do not require the addition of water or electrolyte. These batteries are charged and maintained in a fully
charged state by the main power supply’s charger during normal system operation. The charge current is 1.0 A, a discharged battery typically reaches the voltage of
27.6 V DC within 48 hours
