Hello, New to all of this.

[matt421]

I have a chance to purchase a GNB Indurstrial Power 50G1 2 Volt 264 AMP Hour Battery from a distributor. New not used with cell dates of 05/06/13. 14 of them. Could and Would this be a good choice. Under $50 a piece. Thanks for any help. Also I was looking for an all in one inverter of Samlex EVO-3012 3000 Watt Pure Sine Inverter/Charger. I havent figured out the solar panels yet. It is going to be for a mobile trailer/home. Again thanks.

STOP. No they would not for a variety of reasons:

"New" does not mean well-maintained, unless you can vouch for their maintenance. If they just sat around for two years in the back of a hot loading dock, you may have problems with hard sulfation that you can't recover from. If the guy you buy them from just hammers them for a few hours with an auto-parts-store charger just prior to your arrival, you may be fooled into paying them $50 each for the privilege of recycling them yourself.

You don't yet know your own power needs measured over time. Thus, these batteries may in fact be too small for what you require, even if in perfect condition. And, the solar array to keep them properly charged in the first place is also in question since you don't yet know your power needs.

Instead of spending money on batteries right now, spend that on measuring equipment instead, like a P3 International Kill-A-Watt meter to start measuring your watt hour requirements for each device you plan on powering, and for how many hours a day.

Could and Would this be a good choice.

To extend what is behind PN's advice, determining if a *system* (not just one or two components) is a good choice requires several steps.

1. Determine your daily energy usage
2. Reduce your expected consumption where possible - off grid solar is more expensive than electricity
3. Determine your worst case sun conditions - insolation where the system will be located
4. Determine if you will have partial shading - even small areas of shade on a solar array can substantially reduce output. Shading can be mitigated to an extent in various ways (eg micro inverters, strategic placement of panels in each of parallel strings, etc) depending on your situation.
5. Design a system one step at a time (there should be a sticky here, or Google it), using the information gleaned in steps 1 through 4.

The components of a PV system need to be matched to each other, and matched to your energy needs and conditions. Determining battery bank size is one of the last steps, not the first one.

Thanks for the info.

Hello ri****ha and welcome to Solar Panel Talk

It is considered impolite to put piggy back your first post on an existing one. Having two in the same thread will get a Moderators attention.

Please open your own thread in the New Comers area and lets us know a little more about yourself and your interest in solar.
