-5% SaleHigh-efficiency 2.5kW pure sine inverter with 24V battery architecture, 3000W 500V MPPT solar charging, and 5000VA surge capacity.
The Knox Argon 2500 (Model: 2.5kW-24-pV3000) is an off-grid solar inverter engineered for mid-sized domestic residences, commercial offices, and retail backup systems requiring balanced 24V storage efficiency and higher sustained wattage. Operating at a continuous 2500W rating across both utility bypass and battery inversion modes, the Argon 2500 eliminates the power de-rating common in lower-tier units. It operates seamlessly on a two-battery 24V bank, keeping DC current draws manageable while supporting up to 3000W of solar photovoltaic input. Designed to overcome chronic utility voltage sags, the unit incorporates an ultra-wide AC input range of 90VAC to 280VAC in appliance mode. This feature allows users to charge battery banks and power AC loads directly from dirty or depressed utility lines without wasting valuable battery cycles. With pure sine wave AC output (220/230VAC ±5%) and a 10ms transfer time for computing systems, it protects sensitive microelectronics, IT networking equipment, and home appliances from unexpected blackouts. ## Key Engineering Advantages - 2500W True Continuous Battery Output: Delivers a full 2500W load capacity in battery mode, matching its rated bypass power and giving users reliable power for heavier simultaneous loads without unexpected shutdowns. - High-Voltage 3000W MPPT Solar Charger: Features an expansive 30VDC to 500VDC MPPT tracking window with a 500VDC open-circuit limit. This allows users to wire 5 to 6 modern high-wattage panels in a high-efficiency series string, minimizing cable losses and simplifying array mounting. - 5000VA Surge Capacity (3:1 Crest Factor): Easily handles the heavy inductive start-up currents demanded by 1 HP water pumps, domestic refrigerators, and power tools without causing output voltage dips. - 100A Fast Hybrid Charging Engine: Combines up to 100A solar charging with a 60A utility charger to rapidly restore 24V flooded, tubular, AGM, or lithium battery banks during brief daytime or grid availability windows. ## Compatibility & Application - Battery Chemistry: 24VDC battery configurations (two 12V batteries in series or a native 24V LiFePO4 pack). Fully supports user-defined float (27VDC) and bulk charging profiles up to 32VDC overcharge protection cutoff. - Load Profile: Ideal for powering complete home setups including 1 HP water pumps, refrigerators, entertainment centers, office PCs, security systems, ceiling fans, and LED fixtures up to 2500W continuous load. - Monitoring: Includes an RJ45 communications port designed for external Wi-Fi data modules for cloud-based system telemetry. ## Package Contents - 1x Knox Argon 2500 Inverter Unit (2.5kW-24-pV3000) - 1x User Manual & Installation Guide - 1x RJ45 Interface Communication Cable - 1x Wall Mounting Fasteners Pack
Zener Authenticity Promise: All sitemarks, models, and technical statistics are registered with the factory and verified in our physical laboratory before sale.
For the 24V battery bank, use two 12V deep-cycle batteries of identical capacity and age wired in series with balanced 25mm² pure copper interconnects.
Configure your solar array with 5 to 6 panels (500W–550W) in a single series string; keep the open-circuit voltage around 300V–400V for peak MPPT conversion efficiency.
Install an external 125A DC circuit breaker on the positive battery cable near the battery terminals for rapid isolation and over-current protection.
Keep at least 200mm of clearance around the top, bottom, and side fan grilles to ensure proper airflow through the cooling channels during sustained 2500W operation.
A1: Yes, the Knox Argon 2500 easily starts and runs a 1 HP domestic water pump, using its 5000VA surge capacity to absorb initial motor startup current spikes.
A2: The Knox Argon 2500 supports up to 3000W of total solar panel capacity with an open-circuit voltage limit of 500VDC.
A3: No, the Argon 2500 delivers its full 2500W rated capacity in battery mode, matching its AC bypass capacity.
A4: The Knox Argon 2500 requires a 24VDC battery bank, typically configured using two 12V lead-acid batteries in series or a single 24V LiFePO4 battery pack.
A5: No, the Knox Argon 2500 does not support parallel card stacking; it must be wired as an independent, standalone inverter.
