DS ENERGY 1.5KVA HYBRID INVERTER

DS Energy 1.5kVA hybrid solar inverter with an inbuilt 50A MPPT charge controller is an intelligent power management system that combines a DC-to-AC inverter, an MPPT solar charge controller, and a battery charger into a single unit. It manages power from solar panels, batteries, and the utility grid or generator simultaneously to ensure uninterrupted power supply. 

 Functional Description

- Hybrid Operation: It can run on solar power, battery power, or grid power, prioritizing solar energy to reduce electricity bills.

- Built-in MPPT: The Maximum Power Point Tracking (MPPT) controller maximizes solar harvesting efficiency by up to 30% compared to older PWM controllers.

- Pure Sine Wave: It outputs clean AC electricity that mimics grid power, making it safe for sensitive electronics.

- Cold Start Function: The system can automatically turn on using only battery power when the grid is completely offline.

- Smart Charger: It features a multi-stage battery charger that prolongs battery lifespan and prevents overcharging.

 Typical Load Applications

This size of inverter is ideal for small apartments, offices, or specific dedicated circuits. It can comfortably power: 

- 1 LED TV (43--55 inches)

- 4--6 Energy-saving LED bulbs

- 2--3 Standing fans

- 1 Laptop and 1 Wi-Fi router

- 1 Small inverter-compressor refrigerator (provided the surge power does not exceed 3000 VA) 

(Note: It cannot power heavy heating elements like electric kettles, water heaters, air conditioners, or hot plates). www.dsenergy.com.ng
