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

[Solar Guy Richard]

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.

Nice!

Edit-“well for you guys”. Sorry

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

Yep his video is up!

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

No where? Not even panels?

Nice!

My luck is that you going to come out with a "low frequency" inverter next week thats even a better deal... . Oh well, this one still can handle the surges of my AC and table saw.

Why does Will say it's UL listed? I see the certification by TUV just like so many other products.
Only the EG4 LifePower4 battery is actually UL Listed.

It’s TUV certified to adhere to UL standards. Same as MPP. Is that good enough for permits in most jurisdictions? ?‍

These are HF inverters. Is there a published surge rating? I would need 2 units for split phase 240V output, so if I buy 2 inverters and match them with 3 or 4 Lifepower4 rack mount batteries, can they start a large HVAC condensing unit...say 55A inrush at 240VAC?

Idk about eg4, but the LV6548 i think is 2x capacity for 5 seconds?

Yes, that was what I was saying, it's the same as just about every other low cost popular Inverter and No, you would need it to be UL Listed. They need to be able to look it up in the database.
I was surprised that Will was saying it is Listed, he usually gets his info 100% right.

Likely the MC4 connectors are not allowed for UL because they are not considered a strain relief type connector.

I am surprised in the charger efficiency below from the two spec sheets I know there is a difference in qty of MPPT's not sure if its related..?

	EG4-3000	EG4-6500
Battery to Inverter Efficiency	94%	90%
Battery to Inverter Efficiency	97%	93%
MPPT Qty	1	2

I noticed that also.

The specs for the EG4 says 13kw for 5 seconds. Thats specifically talking about 1 unit @ 120v .. not sure if that translates to 5 seconds @ 240 .. and then what happens if you have 4 or 6 units in parallel .. does that have an effect on the time since the load is split among more units?

 

[Sparky800]

How many watts or amps will it pull from a grid or generator 120v connection? Its missing on the specs. for this and the 3000 model.

Regarding UL listings - UL 1973 is not sufficient for residential battery installation if your state is on the 2018 IRC. Section R327.2 of the 2018 IRC states that energy storage systems (ESS) be Listed (Certified) to UL 9540, meaning the combined battery and inverter (ESS) have undergone fire testing under UL 9540A.

 

[RoySalisbury]

I also just realized ... its 120amp max PV charging current. Is that per MPPT controller (2 MPPT per unit = 240amp) or is it 120amp for the entire unit?

If its per unit, then It's better to do 4k per unit. With all 8k on a single 6500EX, then only about 6K can ever be used to charge the batteries ..and if I am not using 2K for loads, then its wasted power.

(I'm running the numbers so I can size my fuses/breakers/wire correctly).

 

[niktak11]

I also wish it had 100A AC passthrough so 4 of them could power a 200A main panel. With only 60A passthrough you'd need 8 of them (or 7 if you're fine with an imbalance).

Are these inverters as loud as it sounds on the video? It sounded like the fans are on 100% of the time? If so why aren't they temp controlled instead?

 

[ffemt596]

What batteries is it compatible with?
