NPP Gel Solar Batteries

Available specifications and prices

Prices are in Saudi riyals as shown on the product pages, and specifications are taken from the product data itself.

Advantages

• Lower upfront cost per nameplate kWh
• Sealed, no fluid maintenance
• Better heat tolerance than vented lead acid
• Small sizes available for gradual expansion

Points to consider

• Usable energy is roughly half of nameplate (50% DoD)
• Shorter cycle life that falls quickly with heat
• Heavier and bulkier per kWh
• Needs periodic full charging to avoid sulphation

What is actually stocked from NPP

MADAR SOLAR currently stocks 12 NPP models in gel chemistry, at 12V, with capacities from 26Ah to 250Ah.

Installation and usage considerations

Install in a ventilated spot out of direct sun, avoid discharging below 50%, and check each battery's voltage periodically - imbalance in a lead-acid bank destroys the whole bank.

Use cable sized for the current with a short run between bank and inverter, plus a breaker or fuse on the positive terminal. Thin cable and long runs are the number-one cause of poor performance wrongly blamed on the battery.

How to pick the right option

Start from daily kWh and the hours you need, then divide by allowed depth of discharge (0.9 lithium, 0.5 gel) to get required nameplate capacity.

Fix the system voltage from your inverter, then compare options on price per usable kWh rather than price per unit.
