1.5KW -12V

 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. 

Technical Specifications

1. Inverter Output (AC)

* Rated Power: 1500 VA / 1200 W to 1500 W (depending on the power factor, typically 0.8 to 1.0).

* Output Voltage: 230 V AC ± 5% (or 110 V/120 V depending on regional standards).

* Output Frequency: 50 Hz or 60 Hz (auto-sensing).

* Waveform: Pure Sine Wave.

* Surge Power: 3000 VA (lasts for 5 seconds to start motorized loads like small fridges).

* Transfer Time: ≤ 10 ms (for computers/UPS mode); ≤ 20 ms (for home appliances).

 2. Battery & Charger (DC)

* Nominal DC Voltage: Usually 12 V DC or 24 V DC (most high-efficiency MPPT models in this range utilize a 24 V bank).

* Maximum AC Charging Current: 10 A to 20 A (from grid/generator).

* Battery Type Compatibility: Flooded, AGM, Gel, and Lithium-ion (LiFePO₄). 

 3. Solar Input (MPPT Charge Controller)

* Maximum Solar Charge Current: 50 A.

* Maximum PV Array Power: 1200 W (for 24 V systems) or 600 W (for 12 V systems).

* MPPT Voltage Range: 30 V DC ~ 80 V DC (varies by brand).

* Maximum PV Array Open Circuit Voltage (Voc): Up to 100 V DC or 150 V DC.

* Maximum Efficiency: 98%. 

 4. Physical & Environmental

* Cooling: Forced air cooling via variable speed internal fans.

* Operating Temperature: -10°C to 50°C.

* Storage Temperature: -15°C to 60°C.

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) [29] 

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