SPT SERIES
3000W 110/220V Split Phase Pure Sine Wave Inverter
Choose one fixed 24V, 36V, 48V, 60V, 72V, 96V or 110V DC input version. Output is fixed 110/220VAC split phase at 60Hz.
Input voltage selection: 24V, 36V, 48V, 60V, 72V, 96V and 110V are seven separate fixed-input versions. The inverter does not automatically change between battery voltages. Select the variation matching your nominal battery bank.
Product Highlights
Split Phase Output and Load Limits
| Connection | Output | Maximum Planned Load |
|---|---|---|
| L1 + N | 110VAC / 60Hz | Up to approximately 1500W |
| L2 + N | 110VAC / 60Hz | Up to approximately 1500W |
| L1 + L2 | 220VAC / 60Hz | Up to 3000W total / approximately 13.6A |
| Combined Outputs | 110V and 220V loads | Total connected load must remain within 3000W |
Important: Using both 110V legs and the 220V output does not increase total inverter capacity. Keep loads reasonably balanced between L1 and L2.

AC Connections
Recommended Applications
Suitable for RVs, cabins, mixed household loads and daily off-grid systems that require compatible 110/220V split-phase power.
Startup-load warning: Refrigerators, pumps, air conditioners, compressors and other motor-driven equipment can require several times their running wattage during startup. Check the largest startup surge before ordering.
Installation and Safety Notes
- Connect only to a battery bank matching the selected fixed DC input variation.
- Use correctly sized copper DC cables, keep cable runs short and install suitable over-current protection close to the battery.
- Confirm battery polarity before connection. Reverse polarity can damage the inverter and is not covered by normal warranty.
- Do not connect the AC output to utility power, a generator or another inverter output.
- Do not jumper neutral and ground inside the inverter. Follow the grounding and bonding requirements of the completed electrical system.
- Keep the fans and heat sink clear. Install in a clean, dry and well-ventilated location.
- Use a qualified electrician for hardwire terminals, breaker panels, transfer equipment or fixed-building circuits.
Before You Order
- Select exactly one DC input variation: 24V, 36V, 48V, 60V, 72V, 96V or 110V.
- Confirm that 110/220VAC split phase and 60Hz match your equipment and electrical system.
- Confirm the required 110V and 220V socket or hardwire configuration.
- List all simultaneous loads and verify the startup surge of the largest motor or compressor.
- Plan the 110V loads so neither L1 nor L2 exceeds approximately 1500W.
