What we found

Battery models are matched as running it across several brands, by setting each maker's published figures against the other — neither names the pairing.
11 batteries are compared as NOT suitable for it, by setting each maker's published figures against the other — neither names the pairing.
Specifications are published for it, each with its source.

At a glance

System voltage 12 VContinuous draw 200 A

Battery and charging

Peak output: 4000 W peak
Continuous power: 2000 W continuous

Other findings

Max current at max load: Draws up to 200 A from the house bank
Peak efficiency: 90% peak efficiency
Transfer time: Transfers in under 50 ms, between 95 and 135 VAC
Under voltage shutdown: Shuts down at 10.5 V, restarts at 12.0 V

Batteries documented to run this

The figures below line up. Neither manufacturer states that this pack runs this device — that is our reading of what each of them published separately, not a claim by either of them or a test by us. Even where every stated figure agrees, these can still decide it:

The device’s published draw is usually a peak, not the load it holds — the two numbers are not the same kind of quantity
A maker’s amp-hour minimum and their reserve-capacity minimum can give different answers about the same battery
Conditions attached to the chemistry, such as a speed limit for running on lithium
Whether the pack may be wired in series at all, where the device needs 24 or 36 volts
The charger, which both makers put conditions on and neither supplies
Case size, hold-down and terminal type — fitting the space is not being secured in it

Worth confirming with the device's manufacturer or a dealer before buying.

Renogy rate this pack at 200 A continuous — their datasheet reads "200A" — and Progressive Dynamics publish a max current at max load of 200 A for the PD1620. The two figures are EQUAL, so a pack running this inverter at its full 2000 W would be at its maker's stated limit with nothing spare. That is a different statement from a comfortable fit, and neither company has made either. Compared on continuous figures only: nothing here is about surge.

Neither company names the other and nobody has tested the pairing.

Batteries documented as NOT sufficient

Renogy rate this pack at 100 A continuous — their datasheet reads "100A" — and the PD1620 draws up to 200 A at full load by Progressive Dynamics' own figure. The pack is not rated to deliver that continuously, short by 100 A. Neither company names the other, and this is a comparison of two documents rather than anybody's refusal. Compared on continuous figures only: nothing here is about surge.

Redodo rate this pack at 100 A continuous — their datasheet reads "100A" — and the PD1620 draws up to 200 A at full load by Progressive Dynamics' own figure.
