MPP Solar LV6548V 500v is not a "Hybrid?"

Hi, I'm trying to learn about this model. Does it not have the built-in capability to combine multiple energy sources and same level of flexibility and integration as a hybrid inverter like the HYBRID LV 6048?

Thank you.

In reference to solar equipment.

"Grid-tied" pushes all available production to its grid connection. And relies on the grid to function.

"Off grid" stores production in a battery for current and future use. And does not need the grid to function.

"Hybrid" is a combination of both above.

Okay, thank you timselectric, it appears to me this unit can do everything the hybrid models can do: push power to grid and/or batteries and does not need grid to function, but I could be wrong.

Just to add some clarity (or perhaps confusion) Here is how MPP Solar defines "hybrid". Others may or may not use Hybrid Inverter to mean the same thing. The issue of Grid Interactivity (UL1741SB Compliance) has to be included in the understanding Inverter capabilities and limitations.

All-In-One does not necessarily = Hybrid

From MPP Solar Website.
"Off-Grid inverters are defined as the inverter is only able to draw power from grid for backup, when it becomes necessary. Power flow to AC input is therefore one-directional. Hybrid inverters however are able to extra power to grid when there is surplus PV power and therefore power flow to AC input is bi-directional. It’s important to recognize that all Hybrid inverters can operate as Off-Grid inverters, but not vice versa."

Correct
AIO's come in 2 varieties.
Off grid and hybrid

I never anticipate wanting to give power back to my local utility. However, I was somehow under the impression that in an off grid situation, the "bidirectional" power flow capability to the (now absent) utility is nonetheless potentially useful, but I'm having trouble seeing how. Is it just that it could be used simply as another A/C output? At the risk of ridicule, I'll ask: In an off grid situation, what about having two such AIO hybrid inverters (w/ separate panels and batteries) , not paralleled, but connected to each other via their unused hybrid grid-tie inputs/outputs? Back up battery bank? Does this add any advantage to just paralleling them w/ same number of panels and batteries?

No
The input is disconnected, when no grid is sensed.
You could connect one output to another input. But that can limit the total output of the system, in some situations.

ok thanks , I had a strong feeling my idea was boneheaded since I posted it.

Nah
You don't know, if you don't ask.
