Frequently Asked Questions

Clear answers to common questions about this product, setup, compatibility, and use.

Is the NOVA 6548 (RS-H6548) large enough for appliances with compressor or motor startup demand? The NOVA 6548 (RS-H6548) is rated for 6500VA/6500W of continuous output and 2* rated power for 5 seconds of published peak or surge capability. Compare both the running demand and the actual startup requirement of every simultaneous load. A motor, compressor, microwave, or pump can still overload the inverter even when its normal running watts appear to fit. What battery voltage must be planned around for the NOVA 6548 (RS-H6548)? The published battery-side voltage is 48 VDC. The battery bank, BMS, busbars, fuse, disconnect, and cable path must support the inverter's continuous and startup demand at that voltage. Do not substitute a different nominal battery voltage because the AC wattage looks similar. What type of AC power comes out of the NOVA 6548 (RS-H6548)? The published AC output is 120 VAC ± 5% with Pure Sine Wave output. Match the voltage, frequency, phase arrangement, neutral and grounding requirements, and load type to the equipment being powered. A wattage match alone does not make a single-voltage load compatible with a different-voltage or split-phase output, or vice versa. What are the array power, tracking-voltage, and Voc limits on the NOVA 6548 (RS-H6548)? The built-in solar input lists 8000W (4000W x 2) of maximum PV array power, an MPPT operating range of 90 ~ 230 VDC, and 250 VDC as the maximum PV open-circuit voltage. Check the completed series-parallel array against every published input value, including open-circuit voltage under the lowest expected temperature. Meeting one limit does not guarantee the rest of the string design is safe. How should I evaluate the NOVA 6548 (RS-H6548)'s transfer time for computers and control boards? RICH SOLAR publishes a transfer time of 10 ms (For Personal Computers), 20 ms (For Home Appliances). That may be suitable for many appliances, but it is not a universal guarantee that every computer, medical device, control board, or communications load will remain uninterrupted. Compare the load manufacturer's ride-through requirement before treating the inverter as a UPS. Can the NOVA 6548 (RS-H6548) be paralleled when the system needs more output later? The official specification lists the parallel capability as Yes, 6 units. Expansion still requires the approved parallel hardware, identical compatible units, correct firmware and configuration, adequate battery and PV capacity, and a properly designed AC distribution system. Do not mix models simply because their individual voltage and wattage ratings appear similar. Which monitoring or communication connections are provided on the NOVA 6548 (RS-H6548)? The published communication interfaces are USB/RS232/RS485/WiFi/Dry-contact. Confirm which adapter, application, network device, or cable is required for the specific interface you plan to use; the presence of a communications port does not mean every remote-monitoring accessory is included in the standard box.
