This module includes a DC to AC true sine wave inverter, an AC transfer switch and a battery charger kept in a modular type of box made of powder coated steel. The TSW4048 flexibly meets the requirements of 120 or 240 V AC power at 60 Hz frequency as well as 230 VAC at 50 Hz frequency easily.
This compact inverter measures 572 mm x 229 mm x184mm in size and weighs 22.23 kg thus allowing installation even in space constraint positions without difficulty. The TSW4048 inverter charger offered by Apollo Solar does not require external transformers for performing step up, step down and balancing functions thus saving on costs and installation time. The continuous power rating of this module at 25ºC is 4000 VA and its nominal DC battery input voltage is 48 VDC and its input current is 92 A. The AC output frequency of this module is 50 or 60Hz +/- 1% and its AC input frequency range for charge mode is 46–55Hz at 50 Hz, 55 to 65Hz at 60Hz nominal. The AC input maximum current is 120VAC: 40A, and 240VAC: 16A.
This module conveniently operates in temperature ranging from -20 to +45°C. For the purpose of communication this inverter incorporates ASNET (RS-485) and CANBUS type of data communication. The TSW4048 model meets the certification requirements of UL 1741, CSA C22.2 No.107.1-01.
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 4-stage charging algorithm--Bulk, Absorb, Float, Equalize--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 Apollo Solar ASNET - Network Kit port provides networking capability of multiple units, access to the T80/T80HV MPPT Turbocharger Controllers, and to the Apollo Remote Displays, for optimized system design. 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.
