OK my friends, check the photo of the CC bottom left is the brand I did some Googleing found the home page under new e-tracer charger and found a lot info and specs, found a photo of the CC connected to laptop for reprogramming using RS232 serial port same I use to recover dead satellite receivers........any light once you read that specs will be good, anyway I thinkuuncle already bought this kit instead of the one in amz last night, if I heard wrong it doesn't matter because wish ever kit I receive I will upload photos and ask your advise before installing it.........AZ

This is what I found, copy paste with android phone is not fancy sorry for that, still waiting on seller to confirm but I think the CC is the 60 amp model...........brb still research. AZ

Hard to say with any accuracy since this one's description only covers the panels in any detail.
It has a total of 1000W of panel, which is good. But those panels are small battery-type panels (low voltage), which is not bad in itself but is usually not the least expensive way to get any particular amount of total power.
Pure sine inverter is good too, and the panel power is better matched to the inverter power. The CC is supposed to work with 12, 24, or 48V battery systems, but we do not know what voltage the inverter is designed for.
A lot of missing information.

Let me try to find the specs and copy paste here................AZ

I replaced the dot com to xxx........compared with the kit my uncle is buying with this one wish do you think is best? Both are the same price but this one says the inverter is pure sine wave..........AZ

My system cost me $20,000 US dollars give and take few hundred dollars for the exchange rate changes during the whole system setup. I have 12 235 watts panels wired in 3 series string connected to a OUTBACK FM60 CC. 8 250 watts 8 245 watts panels wired in 4 series string connected to a Classic 150 CC. 1 bank Rolls S-460 8x6 volt connect to a Midnite 250 amps breaker/combiner. another bank Rolls S-530 8x6 volts batteries connected to another Midnite breaker combiner box. the inverter is Magnum MS4448PAE 4400 watts 48 volts.

My daily power usage is about 20 to 25 KWH,( mostly 22-23 KWH). According to the CC logs my harvest daily between 20 to 35 KWH depend on how many clouds passing by, rainy days is about 5 to 10 KWH, I use a 4400 watts generator and grid for rainy days. I put most my consumption in the sunny time, the battery supplied power is around 10 KWH each night.

Cheers.

That is a pretty good price for your system. Conservatively figuring 25 kWh a day harvest that would come to about 45600 kWh in 5 years. That calculates to about $0.44/kWh which is much lower cost than I usually calculate for a solar battery system. Of course if those batteries only last 4 years then it drives the price up to about $0.55/kWh which is still very good. Thanks for the data.

No problem at all. You are paying attention and learning - learning before spending is a lot more cost effective than the other way.

Have a great day!

Great day to you to my friend...............now that you mention scale it is good to know because I thought this was an individual setup for a moment I thought it was a kit for each appliances, I thought one inverter for the fridge one for the TV and so on and on, I mention the magnum to my uncle and he asked if its proper to have 1 inverter for the whole house and just thinking if something goes wrong with the inverter I loose all the energy, if it was wiser to have more then one inverter and if something goes wrong I only loose energy to that part of the house and everything else has energy? I see the logic of his question and I ask, if his question is valid? AZ

AZ,

If you are going to build a PV system more than 500 watts, A MPPT CC is a must. The Classic 150 is one of the best MPPT charge controller you can get now and it will scale, you can start with the Magnum MS4448PAE Inverter/Charger and the Classic 150 with 4 250watts panels and 4 6volt Golf cart battery 220 ah. you sure can power the fridge and few LED lights and the satellite receiver and the TV for a while, later you can go with 4 more panels or 8 more panels with larger bank batteries.

Those golf cart batteries may last you 2 to 3 years depend on how you care them. after that you can buy a bank of those Rolls or Trojan batteries according to your need. The inverter and charge controller both can use either 24 volt or 48 volts battery bank. that is the only scalable from small to medium system I can think off.

AZ,
Just remember the components in solar system don't scale well. You may have to replace all of them except the panels. so try to determine what you want long term and buy accordingly.

If it is me, I would buy one of the Magnum MS4448PAE or something similar, it cost around $2000 US and a Classic 150 Charge controller which around $650 US. Then you can buy the panels and batteries according to what you can for the time being. At least the inverter and the charge controller will give you 4000 Watts continue power if you need it.

Thanks for those details, Magnum MS4448PAE is the model right? Let me add that to the list as a must, by the way I read info on difference between PWM and the other type of charger but still a bit confused, in simple words what exactly is the difference and wish in your opinion is better?..........thanks in advance AZ

At least the inverter and the charge controller will give you 4000 Watts continue power when you can buy more panels and larger bank batteries. The inverter also is a charger so you can charge the battery bank with the generator.

That is a nice setup, I am sure I can end up having a nice setup but not bought at once it will be a little at a time, my in law said his brother started a bit a time and said this was like a drug, the more he bought and installed the more he wanted, once he remember helping him installing a few solar panels and while he was installing he was already saying the next thing he will be buying...............AZ

[paulcheung]

You are correct he will need more panel wattage or less battery but without really knowing what his daily kWh load is I am just guessing.

Remind me again what your system includes; panel wattage, batteries, CC, inverter, gen set, etc. and what was the approximate cost. I would like to know what an existing solar battery system costs and how much kWh is it can safely generate in a day.

Russ my Bad I thought that was the name of the brand not the seller, as a mod from another forum I apologize and will be more careful.................... Since I understood the concept of solar let's forget the tittle of 24/7 refrigerator and let'sgo with the fridge ON during the day with solar and batteries and OFF during the night, also by the kit I told you my uncle is sending me some of you already mention is not enough well until I fully learn what you guys know for years, with that knowledge that kit with what amount of batteries you recommend and could be enough for? Just an example the TV with satellite receiver and internet modem? Also remember I have a 4,000 watts generator that I can combine or alternate use between the kit a gen set..............
My in law called me last night, he said he did some changes to his house to remove some stress from the bbatteries, all the lights are now 12V LEDs.,.....,..................AZ

[AZlink]

All good info, also I can use fridge for an amount of hours and then unplug during the night, while we sleep the fridge will not be open then in the morning when sun is out plug it back in, I already made my mind to adapt and make all this ideas.....thanks to you all and your time.....AZ

According with my uncle he can change in the order the charger controller from PWM to MPPT, he mention a friend of him suggested that solar kit, he mention all info and details of all the parts are available at BS or something like that dot com, doing some Google right now to see what info I can find, thanks again to you all..........AZ
