Hi everyone.
My 1st post.
I have ordered anAC500 and 2 B300k batteries. They will come with a 140(?) to 90 cable and a 90 to 90 cable.
So I will be connecting one battery direct to the AC500 and the one battery to the other B300k.
My question is will this give me the full 5000W AC output or the reduced 4000W(?) output that I would get with a single B300k?
Or to put it another way, should I be using 2 140 to 90 cables, connecting both batteries directly to the AC500 to fully utilise the inverter capacity of the AC500.
Hi again. The cable I was referring to is actually the P090D To P150D.
According to the user guide technical specifications, one B300K battery can supply only 3 kW due to the output capacity of the B300K (and B300) battery. You need to add one more battery to the second expansion port of the AC500 so both B300K batteries in parallel can supply the power for the AC500 rated 5 kW at the AC outlets. So you need a second P150D to P090D cable. If you connect the second B300K to the first B300K with the included P090D cable, you will not reach the 5 kW output. The Fusion Box Pro is limited to 30 A at 240 VAC.
BFW, my own setup has two AC500 in Split Phase with the P030A Fusion Box Pro, and eight B300 batteries (24 kWh) using four P150D to P090D cables. I have sixteen 450 W photovoltaic panels supplying the 6 kW per hour of solar power to the two AC500. Under a bright Sun, the batteries are charged to 100% by 3 PM. The 5 kW output is enough for all my electrical appliances (I don’t have a conventional oven which is a large 10k load at 240VAC).
Firstly, thank you so much for your prompt, thorough and informed reply, Raymond. To me this is the very best of the internet - good people giving freely of their time and expertise.
Regarding the batteries, I thought this might be the case. I’ll order another P150D to P090D cable.
We have been living off grid for the last 21 years, but with lead acid batteries and a cobbled together set-up - part Victron, part Tristar, part other stuff. It worked, but always felt like a mad and on-going science experiment. So we are looking forward to a simpler, more user-friendly system.
Thanks again.
No matter how you connect, they will give you the proper 2750/2800x2 ± output, whatever the new output is for those K batteries. Not sure what you mean by reduced 4000w.
Second, You should not need to get another cable because each battery comes with its own cable.
Personally, I would connect each battery to a separate lead instead of together on one. I bought a 300 with 2 batteries and separated them…I think it works more seamless. I bought a third and that one i daisy chained. When I get 4th then it will go on the other single. Make sure you use them/drain them and the entire system shuts down.
Thanks for your reply, Luke.
A bit of confusion I think. It’s not the battery capacity (Wh) I am concerned about. It’s the maximum AC output from the inverter in the AC 500.
Thanks again for responding.
