12.8V 300Ah Solar Nyumbani Lithium-Ion Battery

12.8V 300Ah Solar Nyumbani Lithium-Ion Battery – LiFePO₄ Cells, Long Cycle Life, Built-In BMS

3️⃣ PRODUCT OVERVIEW

The 12.8V 300Ah Solar Nyumbani Lithium-Ion Battery is a high-capacity energy storage solution designed for reliable home and light commercial solar systems. Built using advanced LiFePO₄ (Lithium Iron Phosphate) cells, it delivers stable power output, deep discharge capability, and significantly longer lifespan compared to traditional lead-acid batteries.

With a usable energy capacity of approximately 3.84kWh, this battery supports essential household loads such as lighting, TVs, routers, security systems, and small appliances during outages or off-grid operation. Its integrated Battery Management System (BMS) protects against over-charge, over-discharge, short circuit, and temperature extremes—critical for Kenyan operating conditions.

Macire verifies every unit for authenticity, electrical performance, and compatibility with Solar Nyumbani inverters. Macire also provides technical guidance, system sizing support, and nationwide delivery.
