Chris & mates,
Congratulations on the production of your inverter. It is much needed in our business.
1) What is the THD of the wave form?
2) On an o-scope will it look like the stepped wave of a Xantrax SW, or more like an Exeltech's smooth sine wave?
3) How many watts will the FX-2000 surge to?
4) How many amps will the battery charger work at?
5) And what do you mean by "smart" battery charger?
6) How much does the FX-2000 weigh?
7) Physical dimensions in inches?
8) Warranty will be?
9) Is your inverter designed to work with other disconnects besides Outback's?

Here you go... Thanks for the questions!

1) What is the THD of the wave form?

Typical voltage THD of the inverter is around 1% - The current THD when selling will be less than 5% total, 3% any single harmonic as required by UL1741 and IEEE929.

2) On an o-scope will it look like the stepped wave of a Xantrax SW, or more like an Exeltech's smooth sine wave?

It is very similar to the exeltech's waveform (i.e. 20K+ switching freq). Not similar to the SW (low frequency) waveform. There is a picture of the actual waveform in an Energy Outfitters advertisement in the current issue of HomePower magazine.

3) How many watts will the FX-2000 surge to?

We are still working on the protection circuitry and determining this critical setting. Its motor starting ability will be similar to a SW4048. This is a very powerful 2 kW inverter/charger.

4) How many amps will the battery charger work at?

The battery charger looks like it will be rated for a minimum of 60 amps @ 24 vdc and 30 amps at 48 VDC. The AC transfer switch is rated for 60 amps AC and the charger includes back-off to prevent overloading small generators.

5) And what do you mean by "smart" battery charger?

This refers to the ability to be programmed for several different charge techniques by the installer. You can select 2 stage, 3 stage etc up to 5 stages and even allow for periodic rest periods for the battery to settle between stages or maintenance charging cycles. Equalization charging can also be programmed based on several different factors.

6) How much does the FX-2000 weigh?

About 60 pounds. The entire chassis is made from aluminum castings and the inverter itself is gasketed and sealed (although there is a pressure equalization valve). The AC and DC wiring compartments are external and are designed to be splash and spill proof when the removeable covers are installed.

7) Physical dimensions in inches?

When wall mounted the inverter is 16.5" wide, 8.5" tall and 10" deep. There is a 2" conduit adapter for the DC end that adds 2.5" to the width. There also is an AC wiring compartment extension that fits on the AC end that adds another 2" to the width - making it a total of 21" wide (same as a SW inverter - surprise!). You should be able to get two of the FX2000s in the same space as a single SW inverter.

8) Warranty will be?

We are looking at offering a standard 2 year "replacement" warranty (parts and labor)and an additional 3 year extended parts only warranty for a total of 5 years. We have designed the inverter to allow for easy repair and servicing - there are only three circuit board assemblies and eight screws to remove the top casting. This can be done on the wall in the field even. What do you think it should be?

9) Is your inverter designed to work with other disconnects besides Outback's?

Other disconnects can be used - there is an optional conduit adapter which connects the DC end of the inverter to the DC disconnect and is designed to match the four 2" knockouts already located on the PSDC. Why would you want to use anything else?

Hello,
Can you describe idling current and/or standby function if any (sleep mode), and any sort of time-of-day programmability? Can DC input be disconnected without losing programs?

Thanks - this is not urgent,
Eric

Yes the DC can be disconnected without loosing the settings.

There is several new modes of operation for systems with PV and utility connections that we will be explaining in detail in the near future.

Hang on to your hats! This is gonna be interesting...

Regarding line #8, about the warranty.
Can the boards be changed by the "wrenches" in the field without having to send the inverter back to the factory or service center in case of a failure? Without voiding the warranty?

Field servicing of the inverter is our goal - for those who are qualified (of course) and have a minimum of equipment (such as a good RMS meter and appropriate power supply - maybe a O-scope, etc.). There are a few issues with listings and such that may be a problem (really only with utility line tie systems in some areas).

The inverter will be very easy to test and service, especially compared to the other inverters available - but we hope that it never needs it of course! We are including some very innovative built-in test / fault indication features to make the repair / troubleshooting easier and more successful.
