I have decided to go with the KISAE Abso 1000 inverter/charger and pretty much have it installed.
The question I have is if I leave the converter installed but not powered with 120 volts can I leave the 12 volt output leads attached to my fuse panel or should I install a contactor to fully isolate it when not in use? The 12v battery feed is piggy backed from the terminal lugs where this is landed on the fuse panel.
Since I finally found the converter and it's close proximity to the power distribution center and where I decided to mount the inverter/charger I am installing a breaker dedicated to it and plan on installing a mechanical interlock between this breaker and the inverter breaker. And will also install a sub panel for the power from the inverter in a cubby hole just above the main panel.

Thanks

I believe it couldn't hurt to put a disconnect between the inverter its power source. A few bucks and effort now could save big bucks and lots of effort later.

Yes the power will not back feed into the old converter.

I just pulled the AC black wire out of the converter breaker.

Hi, I also was talked into trying the Kisae Abso 1000 by DonRowe sales guy. THis thing is a long beast. I am figuring out how to install all this in my Lance camper. This whole inverter/solar project might be total overkill in my small RV? May be worth more than my 93 lance?
Page 6 of the manual says to install a 30 A breaker on the AC input to the inverter. Some on my Lance camper thread have questioned this large size as they say the max AC output is only 8.5 amps?
Another note is it says to use #2 gauge wire on the DC to battery with a max 5 feet run... also #2 on the ground.

Some posters on my thread have convinced me to hook up the inverter to my existing camper AC outlets rather than run a few dedicated outlets. This will utilize the inverter <30ms transfer switch. They suggested 10 gauge wire on the AC in to my inverter but I figure I will be fine to run smaller after I get to the new breaker box where I plan to install a 20 am Aircon branch breaker?. It does seem like I could go with a 15 amp breaker to the inverter? But the darn instructions?

I too plan to disconnect my old converter (Magnetek series 6300 POS RIP) and just connect DC from the inverter to this old DC buss bar. you can see my wiring diagram on my thread.

I understand electricity just enough to get in trouble so I am open for any and all comments

Ok so I have this puppy installed. Haven't really checked it all out but it does have a few issues. If you use the control panel remotely there is a big cubby without a cover. The real problem is the AC in lug set screws that clamp the wire are angled towards the mounting surface. I needed a Chapman mini ratchet. The ground lug is behind every thing. The line out labels are hidden after hooking up.

Converter program seems limited. Charger current setting limited to four choices.
Bulk/Float
5a/1.5a
10a/2a
20a/3a
40a/4a
I have one 115 ahr battery. What to choose?

You can select 4 battery types. Flo,gel,ag,fixed 13.5
In flo=flooded you have these stAge voltages not changable. No finish stage.
Bulk/absorption/Float
14.4/14.4/13.5

I think I want
14.8/14.4/13.5

For a single 115Ah battery I would probably go with the 20A bulk rate.

elkski · 08-12-2015, 04:46 PM

That's what I chose. I think I will just leave it on solar mostly but I need to worry about sulfation with my low < 6 a panel

Should have my install finished this weekend. Yes, the 120 volt in lugs are a PIA to get at when the inverter is mounted. I ended up taking the inverter off the bulkhead it was mounted to and doing this wiring then re mounting it.
Other than than that it was pretty much straight forward, just a bunch of trips in and out of the fifth wheels basement, lucky it is a pass through with doors on both ends, but I've been in tighter spots when riding submarines and working on sonar gear. You wonder if the shipyard had built the boat around the gear!

Anxious to hear how the Kisae works out long term. Terrific price for a PSW inverter\charger.

wa8yxm · 08-13-2015, 02:46 PM

You may leave it attached.. no problem

I have both a prosine 2.0 (2,000 watt true sine wave + charger) and a Progressive Dynamics 9180 with wizard. I leave both attached,, As it happens my preference is for the 9180 over the Prosine (I like the program it follows better) so I keep the prosine's charger "in reserve"

Comes in handy when the plug for the 9180 accidently gets pulled. and it's 3 am and the batteries are failing and I do not want to go out and plug it back in till sunup.

I got the Kisae 1000 install completed over the weekend, turned everything back on on Sunday and all worked fine.
One question I have is how long should the charge run on bulk? I have two Diehard group 24 deep cell batteries and left the charger set at the factory setting for flooded cells which is 40A/4A. I check the fluid level and charged the batteries individually with my shop charger while they were out of the camper during the install.
I am not sure of the age of these batteries as they were installed by the previous owner.

Thanks

Now that you invested in a nice inverter/charger, it may be time to upgrade your batteries.

I don't think Sears sells true deep cycle group 24 batteries, so you probably have 2 group 24 hybrid deep cycle/marine batteries. Since they are of questionable condition, you may be disappointed with the performance of your setup.

I would install ,2 GC2, 6 volt batteries, wired in series to supply the house loads and 1000 watt inverter. You can pick them up from Sam's Club or Costco for 90 bucks a piece. Battery + has them for around 100 bucks and NAPA gets 125 for them. I have Sam's and NAPA in 2 separate banks on my boat and Sam's in the MH.

A GC2 battery is built for rugged use in electric golf carts in a deep cycle situation and hold up well. Otherwise there wouldn't be millions of them moving golfers around day after day.

The footprint of GC2 batteries is close to the GP24, so fit shouldn't be an issue.

mcbarsranch · 08-24-2015, 06:11 AM

I purchased a pair of 215Ah GC2 batteries from Sam's Club and have them installed. Any recommendation on which amperage setting I should use while charging? 40A/4A or 20A/3A. Also how long should the bulk charge take and what voltage should I be seeing out of the charger section of the Kisae 1000?
