Re: need dual battery cables if I only have 1 string?

I was able to pull the 4 cables through the 2" EMT without much trouble--did a careful job taping them tightly together and pre-lubed the conduit before the pull. Pretty short run with just one 90 degree elbow. Thanks for the advice, everyone. Cables are rated for 105┬░C incidentally, so I should be...

Re: safely connecting a battery bank

Whether or not I hire a tradesman to make the initial connection, it's important for me to know how to properly connect and disconnect the battery bank because there may be situations down the road where that needs to be done and a tradesman is not available. I probably should've hired a company to ...

safely connecting a battery bank

Just getting ready to put my grid-tie with battery backup system in service (inspector coming Friday!). I have 8 6 volt lead acid batteries wired in series (Rolls Surette S-550). I've wired them together and the cables to the inverter are wired at the inverter, but I held off on connecting those to ...

Re: need dual battery cables if I only have 1 string?

So what the Outback rep. told me on the phone is wrong? I need to double up on those battery cables then? And I need to double up on the short cables connecting the batteries together in series as well? Plus a second fuse block? (I was going to install a 200amp class T fuse on the positive cable). T...

need dual battery cables if I only have 1 string?

Just finishing up wiring my FPR-8048A. The manual calls for dual 00 AWG cables from the battery bank to the inverter. A guy I spoke with on the phone at Outback says since I only have one bank of batteries (8 6v Rolls S-550, 428 AH), I'm fine with just one pair of cables. Can anyone please confirm t...

Re: battery bank disconnect

I have another question now: the 8048 manual calls for 2 sets of 2/0 AWG cables from the battery bank to the inverter. Do I need another 200A T fuse, so each positive cable has it's own fuse? And do I need to double up on the cables connecting the batteries to each other as well? There is just a sin...

Re: battery bank disconnect

Thanks everyone. I ordered a 200A T fuse to put on the positive cable right near the battery terminal (although I only have 1 string). Am just picking up 8 Rolls-Surette S-550 batteries later today and my CEO is coming to inspect next week. If all goes well I'll be online late next week. It's been a...

battery bank disconnect

I'm installing a small (400 amp hour) 48V battery bank as part of my grid-tie with battery backup system using the Radian 8048. Do I need a disconnect switch for the battery bank, or can the breakers installed in the Load Center serve that function? The battery bank will be located roughly 6 feet fr...

can the 8048A handle a conventional well pump?

Putting together a grid-tie system with battery backup centered on the 8048A, wondering if it can handle the initial current spike from a conventional well pump. I havent been able to directly measure the power usage, but it runs off a 15A/240V breaker in our main AC panel. Has anyone run a conventi...

Re: choosing breaker for main AC panel connection to Radian

Thanks.

So I take it the breaker should be installed at the bottom of the service panel bus? My grid service connects to a main 100A breaker at the top.

choosing breaker for main AC panel connection to Radian

What type of breaker should I install in my main AC service panel to connect with my Radian 8048A? Since power will flow in both directions, I'm thinking it will need to be a particular kind of breaker device but in looking at breakers at stores/online it's not clear to me what I need. Thanks for th...

Re: Radian in outbuilding--need separate ground rod?

Thanks. So I ground the Radian's load center equipment ground bus to a steel electrode driven into the ground? I thought I read in the Outback materials somewhere that the load center should be connected to the main ground at the existing service entrance and there should not be multiple grounds in ...

Radian in outbuilding--need separate ground rod?

I'm in the process of installing a Radian 8048 in an outbuilding close to the house. The existing main AC service entrance and panel are located in the house, and I'm installing a "critical loads" panel in the house as well. A set of underground conduit runs 40 feet from house to outbuilding. Can ev...

Re: minimal battery bank?

Thanks--that's reassuring. I'm pretty sure we're going to want more battery capacity, but that can wait until next year or the year after.

minimal battery bank?

I'm building a hybrid system around the 8048A but could use some advice on the battery bank. Since battery technology seems to be advancing rapidly and my budget at the moment is limited, I'd like to build a minimal interim bank just to get up and running with the Radian, essentially using the grid ...
