The TDM-Plus Series combines pure sine wave AC output with USB charging ports in a compact battery inverter format. It is intended for backup and mobile power packages where customers want clean AC power for compatible equipment while also charging phones, tablets and other USB devices from the same battery system.
Why the Plus configuration is different
The TDM-Plus-500, TDM-Plus-800 and TDM-Plus-1200 provide a capacity ladder from 500 W to 1200 W rated AC output. Each listed configuration combines pure sine wave output with two USB-C PD 3.0 ports and two QC 3.0 ports, alongside a color LCD. This makes the range useful for compact backup packages that serve both AC loads and everyday USB charging needs.
Choose output capacity from the complete load list
The TDM-Plus-500 is listed at 500 W with a 1000 VA peak rating, while the 800 W and 1200 W versions provide more room for larger loads. The peak VA figure is not a guaranteed motor-start capability, and the USB ratings should not simply be added to the AC rating to calculate a combined continuous output. Check running power, starting demand, battery voltage and expected runtime as one design.
Understand the USB charging specification
The product information lists two USB-C PD ports at up to 30 W per port and two QC ports at up to 22.5 W per port. Actual charging depends on the connected device, cable and supported protocol. Simultaneous combined USB output should be confirmed for the exact model, and buyers should not treat the individual port ratings as a promise of full power on every port at the same time.
Configuration checks for international orders
- Confirm the battery input version: 12 V, 24 V or a listed higher-voltage configuration.
- Specify AC output voltage, frequency and socket type for the destination market.
- Match battery cables and protection devices to the expected DC current.
- Confirm the supplied socket layout and USB arrangement because product photos show a configuration example.
- Request the exact model documents, packaging options, lead time and warranty terms.
The TDM-Plus is specified as a battery inverter and does not replace a solar charge controller or provide direct PV charging. For a solar backup kit, pair it with a correctly matched battery, charging system and protection hardware. A clear load list and destination specification will help Gerixi recommend the correct Plus model.
