Re: Small Texas Off Grid System Sizing
Just to clarify Photowhit's freezer specifications. * Freezer is rated for 172 kWH per year * Or 172,000 WH per day * 172,000 WH per day year / 365 Days per year = 471 Watt*Hours per day -Bill1 · -
Re: Little help with PV array capacity.
Is it possible... Yes. Is it something that could "solve" the problem... It would be a waste of energy, Lots of unknowns... How cold, how quick will sun hit panel, tracking or fixed, what i…1 · -
Re: Pros and Cons of different battery types?
That is a huge system upgrade... Have you worked out the daily energy usage, battery size (voltage and Amp*Hours), solar panels, backup genset (if needed), etc.? Flooded cell Lead Acid are relatively…1 · -

Re: Beverage storage area is the coldest it has ever been - 35F
Totally true, personally I don't consider myself a prepper by any stretch of the imagination, I am however almost self sufficient from a food standpoint, but it's extremely difficult to co…1 · -
Re: How does battery voltage translate to watts stored? Does it?
Battery voltage does not directly indicate watt-hours stored. "Standing" voltage measured at least 4 hours after charging or discharging can give you an idea of the battery charge level. BU…1 · -
Re: How does battery voltage translate to watts stored? Does it?
Read this part of your post again. You said 15 watts. (That is per hour, expressed as 15 watt-hours if you run one hour) In the next sentence, you jumped to 15 volts per hour instead of watts. You ha…1 · -
Re: How does battery voltage translate to watts stored? Does it?
Adding to what Marc says... For a first estimate, Lead Acid Batteries are fairly close to 100% "amp*hour" efficient... If you have a 100 AH battery and pull 50 Amp*hours out of it (assuming…1 · -
Re: Off Grid Telecommunications Plant Battery Project
Telcom batteries are designed for only a couple dozen or so discharge cycles, as backup generators come on line. They are designed for long Float life and are often swapped out at about 50% of warran…1 · -
Re: AGM battery Lowest voltage
For most AGM designs, I am a strong proponent of staying in Absorb until end amps are reached, with a limiting timer overlayed. Concorde Sun Xtender specifies Less Than 0.5% of the C/24 capacity at t…1 ·
