When a small backup system needs more than a simple USB supply but does not require a large inverter, the TCI-350 offers a compact starting point for product selection. It is a 350 W modified sine wave inverter with configuration options for different DC battery systems and AC output standards. For distributors and installers, the key is to match the ordered voltage version and the connected load before comparing price or enclosure size.
Where the TCI-350 fits
The TCI-350 is designed around a 350 W rated output and a modified sine wave waveform. It can be specified for 12 V, 24 V, 48 V, 60 V or 72 V DC input versions, while the AC output configuration can be selected for 110 V, 120 V, 220 V, 230 V or 240 V applications. Output frequency is available as 50 Hz or 60 Hz according to the order configuration.
This makes the model useful for compact battery backup packages, small mobile power systems and basic off-grid loads where the product specification and load compatibility are clear. It should not be treated as a universal replacement for a pure sine wave inverter. Loads with motors, transformers, audio equipment or sensitive control electronics should be checked with the equipment supplier before a modified sine wave model is selected.
Match the battery voltage first
The most important selection step is confirming the battery bank voltage. A 12 V version and a 48 V version are not interchangeable, even when the AC output power is the same. Before preparing a quotation, confirm:
- the nominal battery voltage and the expected operating voltage range;
- the required AC output voltage and 50 Hz or 60 Hz frequency;
- the continuous load and the starting surge of any motor or compressor;
- the required socket, cable and protection configuration for the destination market.
Plan the 350 W load realistically
A 350 W rating should be used as a planning reference rather than a target that is held continuously in every installation. Leave practical headroom for startup current, battery voltage drop and wiring losses. For a small backup kit, list each load, its running wattage and its startup requirement. This quickly shows whether the TCI-350 is appropriate or whether the system should move to a higher-capacity pure sine wave model.
The enclosure is listed at 145 x 112 x 55 mm with a net weight of about 0.45 kg. Its digital numeric display can help users check operating information during routine use, while the listed protection functions cover under-voltage, over-voltage, overload, short-circuit and over-temperature conditions.
Questions for wholesale quotations
For a B2B order, a short technical checklist avoids the most common configuration errors. Ask the buyer for the battery voltage, AC market voltage, frequency, expected quantity and main load type. If the same housing will be sold in several markets, keep each voltage version and socket configuration clearly separated in the quotation and packing documents.
See the TCI-350 product page for the current model information. For a quotation or configuration check, send the battery and load details to GERIXI.
