-19% SalePower heavy 3200W continuous loads via 24V battery architecture with 3500W high-voltage 500V MPPT solar and 10ms UPS transfer.
The SUNTEC Newgen 4KVA is an off-grid hybrid solar inverter engineered for mid-to-large residential homes, commercial offices, and light-industrial backup setups facing frequent and prolonged power outages. By running on a 24V DC battery bus, this unit delivers a continuous 3200W (with a 6400VA peak surge) pure sine wave AC output while cutting DC amperage in half compared to 12V platforms. This reduced current flow mitigates thermal stress across internal switching MOSFETs and allows for safer, high-load operation during hot Bangladeshi summers. Equipped with a wide 30V to 500VDC Maximum Power Point Tracking (MPPT) solar charge controller, the unit accepts up to 3500W of solar panel inputs wired in high-voltage series strings. This architectural design eliminates the high current losses and heavy combiner box wiring typical of older low-voltage solar arrays. The Newgen 4KVA manages utility grid power, solar array production, and battery reserves automatically to deliver dependable uninterrupted power for demanding equipment like water pumps, inverter air conditioners, and deep freezers. ## Key Engineering Advantages - High-Voltage 500V MPPT Tracking: The 30–500VDC input window allows direct series connections of standard commercial half-cut monocrystalline panels. Series strings operate at low current and high voltage, which minimizes resistive copper heat loss and reduces cabling thickness. - 6400VA Inductive Motor Surge Handling: Features double-rated peak surge capacity for 400 milliseconds, giving the inverter the necessary power overhead to start inductive motor compressors on 1 HP pumps or 1-ton inverter air conditioners without tripping offline. - 24V Current-Halving Architecture: Generating 3200W at 24V DC pulls a maximum of 150A—half the current required by a 12V system for equivalent wattage. Lower amperage minimizes DC cable voltage drop, cuts battery terminal heat, and extends system service life. - Zero-Reboot 10ms UPS Transfer: When configured in UPS mode, the internal transfer switch reacts to utility grid drops in 10 milliseconds, maintaining stable voltage for sensitive desktop computers, network routers, and commercial CCTV setups without triggering reboots. ## Compatibility & Application - Battery Storage: Native support for 24V battery configurations (two 12V batteries in series or dedicated 24V LiFePO4 packs). Includes a dedicated expansion slot for Lithium battery BMS communication cards to enable closed-loop charge management. - Appliance Loads: Safely manages continuous 3200W combined household or commercial loads. Capable of operating a 1 HP water pump, a 1-ton inverter air conditioner, a deep freezer, 6 to 8 ceiling fans, LED lighting fixtures, and workstation electronics simultaneously. - Solar Panel Matching: Supports up to 3500W total PV array size. Optimally configured with 6 to 7 units of 500W–585W monocrystalline half-cell panels wired in series without exceeding the 500VDC maximum open-circuit limit. ## Package Contents - 1 × SUNTEC Newgen 4KVA 3200W 24V Off-Grid Hybrid Inverter - 1 × RS232 Communication Cable - 1 × User Manual & Installation Guide - 1 × Wall Mount Hardware & Anchor Screw Pack
Zener Authenticity Promise: All sitemarks, models, and technical statistics are registered with the factory and verified in our physical laboratory before sale.
Tracks solar harvest from 30 to 500VDC, enabling direct series connection of up to 6–7 large solar panels to minimize line transmission loss.
Supplies double the rated power for 400ms to overcome heavy inductive inrush currents from 1 HP water pumps, refrigerators, or inverter ACs.
Operates at half the amperage of 12V systems for the same wattage, reducing internal component heat stress and extending inverter operating life.
Detects utility grid failure instantly and shifts power source in 10 milliseconds to safeguard PCs, servers, and sensitive networking electronics.
Includes dedicated slots for intelligent LiFePO4 battery communication cards and Wi-Fi monitoring modules for real-time mobile tracking.
Delivers up to 100A solar charging and 60A AC mains charging to rapidly replenish deep-cycle or lithium battery banks during short grid cycles.
Drawing 3200W continuously on a 24V system pulls up to 135A to 150A under peak loads. Use minimum 35mm² to 50mm² flexible copper cables with an inline 175A–200A DC fuse within 1.5 meters of the battery bank to prevent voltage sag.
Connect six 620W solar panels in series (yielding approximately 250V to 300V Voc at peak load). Operating in this sweet spot allows the 500V MPPT controller to start earlier in the morning at optimal conversion efficiency.
The 6400VA surge capacity easily starts a 1 HP water pump or a 1-ton inverter air conditioner. Avoid starting both high-draw inductive loads simultaneously with heating elements to prevent triggering the 2-second overload trip.
If using two 12V lead-acid or tubular batteries in series to build a 24V bank, install an active battery balancer. Imbalanced series batteries cause one unit to overcharge and boil while the other sulfites and dies prematurely.
A1: Yes, the SUNTEC Newgen 4KVA easily runs a 1 HP water pump or a 1-ton inverter AC thanks to its 3200W continuous rating and 6400VA peak surge capacity. Ensure the starting surge does not overlap with other high-power household appliances like electric geysers or microwaves.
A2: No, the SUNTEC Newgen 4KVA requires an active 24V battery bank connected to power internal control boards and establish voltage reference for inverter operation. It cannot start up or stabilize AC output on solar panel voltage alone.
A3: You can connect up to 3500W of solar panels, which translates to six 550W or seven 500W modules connected in series. The total open-circuit voltage (Voc) of the string must remain comfortably below the 500VDC maximum ceiling even on cold winter mornings.
A4: The 24V system cuts electrical current in half for the same 3200W power draw, dramatically reducing heat dissipation in internal MOSFETs and reducing copper cable gauge requirements. This results in higher system efficiency and longer hardware lifespan under heavy loads.
A5: The 10ms transfer speed shifts from utility grid to inverter power faster than a computer power supply's hold-up capacitors discharge, preventing desktop PCs and servers from restarting. Standard 20ms–40ms inverters cause instant reboots and data loss during sudden grid outages.
