Recommend a good 48v 5000w pure sine wave inverter.

[Sejac]

Any recommendations for a good 48v 5000w pure sine inverter, I do not want to use the solar charger/inverter all in one units. I will be utilizing a Victron MPPT TR VE.CAN 250v/100 controller in the system with 2 litime 51.2v 100ah batteries to start. Thank You

Umm... Victron Multiplus-II 48/5kVA.

 

[sunshine_eggo]

Then a cerbo GX
Then a smartshunt or BMV-712.

Umm... Victron Multiplus-II 48/5kVA.

I would buy the quatro version if going down the victron route. Those really can supply 5 kW vs 5 kva. I have one sitting around in my shop and it is a beast.

IMHO, all victron products ride on it's coat tails.

I am not sure if those batteries can supply that much power or not.

Make sure to include a way to pre-charge the circuit or the BMS might trip - it has a big input cap.

As the owner of 2x 48V/5kVA Quattros, I'll disagree with you 1000%. They are rated for 5kVA. ALL INVERTERS ARE RATED FOR VA. Victron complicates it by putting it up front and then listing different Watt rating. Inverter ratings are for a power factor of 1.0. Go dig into the specs of a Magnum or Outback, and you'll see that while they say Watts everywhere in marketing materials, they actually say VA in their specifications.

If I had to do it over again, I would have gone with the MP/MP-II. At the time I bought my Quattros, there wasn't a 5kVA/48V MP/MP-II. Have ZERO need of a second AC input.

A Quattro and a Multiplus are identical aside from the second AC input.

Yeah. With inefficiencies, it will be at that BMS limit.

I have a 6000w Cnswipower unit, it seems robust in 2yrs+ use so far. They come in virtually any input/output voltage (not split phase though)

If you already have a Victron charge controller, you might as well stay with Victron as Eggo saysand take advantage of the ecosystem.

Otherwise id say the Midnite Rosie is next in line for comparison sake but its more money and a 7k unit.

Here is my logic - might be wrong.

The V 3000 / 48 that I set up for a customer - it maxed out at 2400 watts running a pet blow dryer and another small load in my testing.

My son bought 2 of those 5000 / 48s for a food trailer project in FL, and he ended up just using 1 of them, because it easily ran 6 kW without a problem.

I could be completely wrong, but the quattro seems to be able to run "above" spec, while the mutliplus is just barely able to do it.

Either way, the OP needs 5 kW - not 5 kVA

You should check victron community forum out. Blow dryers are actually oddballs and present substantial issues with many inverters. They are not simply a resistive load and do NOT have a power factor of 1.0.

All VE.Bus inverters can run 30% above spec for 30 minutes.

You are, but I get how your limited testing and anecdotal experience would lead you to that conclusion.

Then OP needs to buy an inverter rated for "6000W" because that's actually a VA rating.

That is the whole reason to use a blow dryer for testing. It is a difficult blended load of inductance and resistance - but typical of a common load that women use. It is perfect for testing inverters, because if they can power that - they can power most stuff.

If an inverter can't easily run:
- 1800 watt hair dryer
- 1800 watt microwave oven
- A similar battery charger
- Home style floor sweeper
- Refrigerator

( one at a time )

Then there is no point in buying it.

Another reason my wife is awesome... we don't have a single hair dryer on the compound.

Now I want one for testing.... but I have some options...

2X rooftop A/C (no soft starts) and a 1500W space heater, minor "background" loads, 3,863W (L2 powers this 5er exclusively):



Add microwave (5,304W):



Can certainly argue the 2X rooftop A/C are NOT friendly loads with a 1.0 PF

And lookee there... (ran the test twice, took about 45 seconds to get the warning)

Heatgun is about as good as a hairdryer for that purpose - same wattage and same mix of inductive/resistive load. I have one I got from HF for $10 on sale that I use for lots of things.
