Signature Solar EG4 6.5K Off-Grid Inverter | 6500EX-48

[RoySalisbury]

These look to be "basically" the same as the MPP LV6548 (and other clones). Notable exception is the MPP model has 250v Voc, and this does 500v Voc.

Plus a $286 price reduction over MPP. And in stock.

I was going to order the MPP version but might as well get this one instead (if its the same thing).

Looks great. I wish it had external CTs and back feeding capability but that's too much to ask for at this price point.

 

[Solar Guy Richard]

Ya, we are really excited about this unit. I honestly don't think you can beat this thing for the price and quality.

What's the idle consumption with the inverter on?

 

[RoySalisbury]

Just ordered 2 ... along with 12 more 330 watt panels. . That along with my 80k battery bank should do me for awhile.

This is for completely OFF GRID use, so feeding back to the grid is not something I need to worry about.

I'm going to guess its close to the MPP version at about 120-130 watt ... Would be nice to be lower, but am not holding my breath.

Our thinking here was as follows:

-Throwing away the combiner boxes and using half sized wire can save at least $1k on a 10+kW system (Plus time/labor)

-The MC4 pv inputs are gone per NEC code for passing permit in most locations

-The EG4 battery comms are native

-Warranty repair and parts based in Texas

-Lifepower4 + this unit is UL1973 and UL 1741 so more people will be able to build these systems in more places with the grid as a "standby power source".

The last item - warranty parts based in Texas is the most significant.
You'll sell tons of these.

70w is what the factory rated it at - I need to test to get a test up to see the actual number. Roy is probably right though.

Since I still have to do a 6x2 array. (45.83 Voc / 9.27 Isc panels) I still need to combiner box. However I am not sure.. Might be able to get away with just using a single MC4 branch. 600v Voc would have perfect. (But this is close enough I guess).

Though the new panels I just got are 10.37 Isc .. and a 6x2 string puts me over the 18A max of the MPPT input.

Whats the headroom on the MPPT input? The MPP one could handle 18A, but was told 21A would be fine.

 

[SignatureSolarJames]

same 22.5 max ISC, so you're safe with 2 strings

no combiner box needed if 2 strings or 1, you can just use a splitter branch for $8

I would like this to go week [jesus-edit-well] for you guys. Please throw some customer service weight behind it.

What’s the deal with mc4 an UL? New to me.

Thanks

 

[Bluedog225]

And have you sent Will one yet? Thanks

 

[Bluedog225]

Dang it. And are comms comparable with the SOK from current connected?

Ok. I’m done. ?

 

[koppted]

Dang, already paid $4000+ for 2 of the MPPs. Patience is a virtue, lol

We are here and Signature Solar is ready for answering a lot of questions.

And have you sent Will one yet? Thanks

Yep his video is up!

Yep, no MC4 to inverter connections allowed for UL systems.

I was actually supposed to order my inverters last friday, but figured since the MPP was out of stock anyway, a few days later would not hurt ... and bingo ... I got lucky.

Will's video shows the EG4 @ 80-85w .. and the "others" @ 70-77w. Still not bad. I was expecting higher actually.

Ya, I assumed it might be a little higher. Very pleased though with the numbers Will got.
