Schneider Conext SW 4048 Inverter/Charger


SKU: 865-4048-21 Category:


Schneider does not provide support to end-users. Warranty processing time is 3-4 months.

The Schneider Conext SW 4048 hybrid inverter/charger is ideal for remote off-grid locations, backup power systems, and residential self-consumption. The SW hybrid inverter system offers a pure sine wave output switchable to 50/60 Hz frequencies as needed.

All Schneider SW power inverters have a 120/240 VAC output and can output 120/240 VAC from a 120 VAC input without an external transformer. In addition, they feature a dedicated input for fuel-based generators to extend off-grid capacity.

The Schneider Conext SW 4048 hybrid inverter/charger can be configured for self-consumption (or zero-export), prioritizing solar power over the grid and not exporting energy to the grid. The inverter instead works with the grid to avoid peak utility charges; it will also support the demand when the utility’s supply is limited. Stack two Conext SW inverters to double the total output power of your system.

There are 2 Schneider Conext SW models available:

Schneider part no. 865-4024-21
Inverter model: SW 4024
Nominal voltage: 24VDC
Continuous power: 3,400W
Nominal power (30 min): 4,000W
Surge power (5 sec): 7,000W

Schneider part no. 865-4048-21
Inverter model: SW 4048
Nominal voltage: 48VDC
Continuous power: 3,800W
Nominal power (30 min): 4,400W
Surge power (5 sec): 7,000W

Both SW inverters support AC-coupled and DC-coupled off-grid configurations and are ideal for applications such as:
– Residential backup power
– Grid-tied solar with backup power
– Residential self-consumption
– Off-Grid solar power systems

Residential backup power

The Conext inverter becomes part of the residential electrical system. It will convert the energy stored in the battery bank into power to run the critical loads. When an extended power outage is present, the Conext SW communicates with the generator to power your critical loads while recharging the batteries.

Grid-tied solar with backup power

All grid-tie inverters shut down for safety reasons when a power outage occurs; therefore, your home will not have power during an outage even with a solar electric system installed. When you already have a grid-tie PV system installed and are selling power to the utility, a Conext inverter will allow you to retrofit your installation to have backup power during outages. While the utility grid is down, you will run your critical loads from the energy stored in the batteries. The batteries will recharge when the grid power is back on. You cannot recharge the batteries with your solar panels in this mode while the grid is down. It is necessary to wait for the grid power to be restored.

Residential self-consumption

Avoid consuming energy from the grid during periods when the rates are at the highest. The Conext inverters will enter self-consumption mode and will prioritize the energy stored in your battery bank and generated by your solar system over the grid power. This configuration will help solar system owners avoid high utility energy rates. Worth mentioning is that Conext inverters feature a ParallelPower mode, where a maximum consumption set point is recorded. The inverter then will support the grid to shave the temporary loads that exceed the peak demand. This feature can be significantly helpful for homeowners subject to tier-based electricity rates.

Off-grid solar power systems

When you are entirely away from the grid, the Conext inverters will function as your primary energy source, simulating the voltage and frequency of the grid. For standard operation, the storage capacity of the battery bank dictates the energy available for consumption. However, Conext inverters are chargers and can be paired with external generators to aid the solar system and battery bank during periods when heavier loads are required.
