The Apollo Solar TSW4048 includes a DC to AC true sine wave inverter, battery charger, and AC transfer switch in a compact modular housing. Providing 4000W at 48V, the TSW is the ideal solution for residential and commercial off-grid systems in the 2kW-12kW range.
With the ISM and the T80/T80HV, the TSW provides a complete off-grid system. The TSW can also be installed separately.

The TSW4048 meets specifications provided by installers, distributors, and dealers and required by end-users of battery-based PV power systems. The result is a single box that provides 120 and 240 volt AC power at 60Hz as well as 230 VAC at 50Hz. With a compact footprint and modest weight, the Apollo Solar TSW Inverter also provides ease of installation in tight spaces.
120/240 Volt AC Split-Phase Input and Output
No external transformers are required for step-up, step-down, or balancing, thus, saving added costs, installation time, and several points of efficiency. The output provides 240 volts for well pumps, appliances, or shop tools while providing 120 volts for standard circuits. 75% unbalanced loads are handled as well. The input can accept the line or 240 volt AC generators. The output can be wired for single 230/240VAC output or for single 120VAC output at twice the current. The option to select 230VAC or 240VAC and to select 50Hz or 60Hz is provided by easily accessible internal jumpers.
200% Surge Power Capacity, Starts a 3HP Motor
Over 200% of the rated power is available to allow for intermittent loads for short periods, like starting a 3HP motor, without interrupting sensitive computer loads.
Parallel Stacking of Multiple Inverters
The TSW Inverters can be wired in parallel to provide additional output current.
Efficient Multi-stage Battery Charging
Power factor corrected, the high-current battery-charging circuit optimizes the efficient use of energy from generator or line input. The 5-stage charging algorithm maximizes both battery life and storage capacity.
Advanced Apollo Solar Data Communications
Monitoring of energy used, battery state-of-charge, and system performance is included. The ASNET port provides networking capability of multiple units, access to the T80/T80HV MPPT Turbocharger Controllers. Remote system monitoring on a local Ethernet and/or on the Internet is provided via the Apollo Solar Communications Gateway and even from sites lacking telephone landline via the Apollo Solar GSM Modem.
