Re: My Solar Project !!! (Questions)
Mr Cormican, is asking these questions (I think)
because ,it is very important to know what you expect to get out of the system you are trying to build.That way he can save you costs and mistakes,that sometimes turn out to be frustrating and costly.
If you live in an area that pays you for the power you may add to the grid, that may be a better option,than a non grid tied system.400 watts of a non grid tied system may not run what you want it to,although, it can help you save on your existing electric bill if you use it for some appliances.
If, you have an outside storage for batteries you can use acid filled, if they have to be inside you need to use sealed batteries and they need to be as close to the inverter as possible.If you are tied to the grid without battery back up you will not have power when the grid goes down,to add batteries to a grid tied system , you add a bunch more money to the system.
Off grid system means at night you will only be working off of the batteries, you may need 8 or more and then,you also need to know what kind of load you are planning at night...do you have enough battery backup?
Inverter choice is important. off grid systems with enough power but not enough surge time from the inverter may,run your washer but not your spin cycle. Instead of one second surge You may want to get a five second surge capability,better for starting motors, wanting a big load.
The one thing which I,did not think about,so I have to plug into the grid for spin cycle,no big deal to me but to some they would be disappointed (actually guess i was disappointed initially, missing this one little detail).An inverter that uses a minimal amount of power when on is a plus also.
An off grid system of 400 watts will not run your waterheater,stove,or dryer.
The systems really are fairly simple but having the RIGHT system is critical for your happiness,thats why you must really take some time ,even write it down on paper,your goals and try to plan your expansion and how you wish to go about it..the cost difference in several of the individual parts/grid/off grid
can be substantial.The learn center here on this site is great and you can also look at the off grid systems on how they are wired and different features.I ,studied and thought for a couple months before deciding exactly what I, could afford and what I wanted to do and it really paid off.
No final decision was made though until I called AltE personally at their store.At this time they made a few points about ground fault breakers and electrical code and grounding.. to make sure I knew what the latest electrical code was on that particular issue.
Rechecked the disconnect panel and controller wiring one more time before throwing the switch and yes..... I,found one wiring mistake I made,fixed it ,a look see one more time
and she has been humming ever since.
A very happy customer
AltE,James and the rest of the crew go beyond the call to help people,they want them to be happy and knowledgeable
with what they are getting and how to use it.
All the best to you and your, soon to be new system.
