Deye Lithium 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

• Up to 90% of nameplate capacity is usable
• Several times the cycle life of lead acid
• Lower weight and volume per kWh
• Built-in BMS for protection and cell balancing

Points to consider

• Higher upfront cost than lead acid
• Requires an inverter with a lithium charge profile or correct manual settings
• The BMS may derate charge current in extreme heat

What is actually stocked from Deye

MADAR SOLAR currently stocks 8 Deye models in lifepo4 and lithium chemistry, at 48 and 51.2V, with capacities from 100Ah to 314Ah.

Installation and usage considerations

Mount in shade with airflow around the enclosure, set charge and cut-off voltages to the manufacturer's figures, and never mix lithium packs of different ages or capacities on the same bus.

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.
