classic 150 12 volt 96 amp limitation work around?

[TomW]

OH IF ANYONE IS HAS A NICE 48V INVERTER FOR SALE I AM INTERESTED SINCE MY SYSTEM IS DOWN I NEED A GOOD QUALITY INVERTER SO I CAN SWITCH TO 48V, THANK YOU . I AM ALSO DESPERATE SINCE I DONT HAVE THE KIND OF CASH FOR A BRAND NEW OUTBACK. I WILL CONSIDER OTHER BRANDS ALSO.

Just a bit of internet etiquette, in case you were not aware of it:

No need to SHOUT.

All caps  is the written equivalent of SHOUTING.

Good luck in your search for equipment. Sadly, the good stuff is pricey.

Midnite tech support has told me that the classic wont be a problem at 100amps, maybe, it won.t be an issue at all.  I will find out more on the telrcom battery, it says its rated for 400 cycle min.@80% dod.

If the classic can;'t handle the load, I won't buy it.  I may buy an off grid 4000 W hybrid pv inverter for $1000. I don;t think it has a 110 volt output though and not for North American use, but still doing research...Thanks for your input..

Now that's a much better idea, install a grid tie PV system and spend your $ on a proper grid tie inverter plus PV panels.
The classic is primarily a battery charging controller and IMHO your design with such a tiny battery is just going to waste lots of PV power and result in wasted $ as the battery dies fairly soon.
I can't quite unsterstand what you hope to achieve with this system design, I doubt it would be economic and save you $ compared to just grid power.

The system i was planning to design was to save on hydro costs and provide some backup power  when the grid goes down. If I do the off grid hybrid inverter, I wont need the classic 150 at all, but will i get the same quality or reliability  I just don;t know.  This looks like China written all over it.

Sorry don't understand what hydro costs means, something to do with water pumping?
Backup power based on a 12v 170H battery where loads can need 100A better only be of a few minutes duration otherwise you will be replacing the battery quite often

OK I meant to say Grid, not Hydro, sorry for the confusion. WHen the sun is out battery draw will be zero, as it is charged by the solar PV cells and will priovide enough to run loads, when the sun goes down, battery will come into play.  It will not be discharged to 100%,  you can set all the depth of discharge to any level you want, make it 10% even. At 10% i could get thousands of cycles out of a battery. It will then transfer back to grid power for overnight, sun comes up charges the batteries via SOLAR only and power loads. Its not that complicated to understand.  I really don;t even need the battery at all, but I think the inverter needs to see it in the system.

Anyway I think I am going to go back to the classic 150, I dont trust this off shore stuff, it sounds nice, but too risky to get parts. I am working on a 48 volt inverter and I will design my own transfer switch for it. It will all be controlled through the aux 1 or 2 outputs from the classic, a well designed feature.

ok, looks like you have a good plan in mind with looking at 48v inverter and 48v battery bank. The  Classic will be moving much less amps at 48v and not be stressed so much.

IMO (for what it is worth) - Go with an Outback Power 24 or 48v inverter/charger with a fan. There are some deals out there and it will take some effort to find them. I sold off some garage stuff on Craigslist to help offset the higher costs of my Outback and Mate 3. It was expensive overall...but, well worth it. Constantly messing with cheap stuff ends up costing more in the future. I went cheap on my batteries...and now looking to replace. So, been there. Good luck.

I have a used Magnum 4448PAE 120/240vac 4400 watt 48v inverter for sale reasonable if anyone is interested email me ryan@kb1uas.com
