Nkdave: nkdave, welcome on board. even though its not really advisable using trailer batteries for inverters, since you say its a temporary solution, no problem. to incorporate solar power for your setup, here is what you need: 170ah multiplied by 1.2 (to account for system losses) will give you: 204ah this gives a total power output of 2448w (assuming you are draining down to a dod of 80 to 100 percent - which may not be practical. for a 5 hour average daily insolation, you can get by with a solar panel array of between 400w to 600w depending on cloud cover. as for your brother, you need to get back to us with actual nameplate power ratings for all the equipment mentioned in your list if you want proper system sizing advice and cost. 1 Like |

Re: Solar Energy, A Complement To FTA by aweso: 9:41am On Aug 14, 2017 |
purplekayc: Crown Deep cycle Batteries are Flooded Lead Acid. Durability of Any Flooded Battery will be determined by 3 factors. Quality Of the Product Periodic maintenance. Rate of Charge and Discharge. Note: Crown products utilize the heaviest and thickest plates available from the battery industry - 10% thicker than those used by batteries like Trojan. More plate thickness delivers longer battery discharge performance and cycle life 1 Like |

Re: Solar Energy, A Complement To FTA by Saipro(m): 9:10am On Aug 15, 2017 |
Before I disappear for another week or two, let me share an experience with you guys: I installed and maintain 3 personal installations in 3 houses (my dad's, a cousin's and mine). We all live within a 1km radius so I just walk from one to the other. Enough about that. I boarded the batteries in mine recently and will soon do a private sale of my dad's batteries (mostly kept on float as he spends half or less of the year in the country). I went against my initial logic of 6V being ideal for RE (had to consider the cost of available 6V batteries) and used 12V batteries (FLA). No sooner had I began using them than I noticed a wide (wild) variation in the cell states. I did a thorough second check and realised the batteries weren't all I had hoped for. No use crying over spilt milk. By serial SG measurents in every cell of every battery and keeping tabs on internal resistance and battery voltage, I was able to group them into good, fair and manageable. The problem? I had only one good one and 3 fair ones. The others were manageable. In a 48V system, it's impossible to keep a balanced charge with such variation in cells. I broke the two strings up and split them into a 48V string (the good and fair ones) and 24V x 2 strings. Brought out my spare Xantrex controller and split the PV array in two. I broke out my new backup 24V inverter too (I had always sought an excuse to give it a test run). I ended up with the same power generation and the same battery bank size but at the cost of extra cabling, an extra controller and an extra inverter. My inverters are both PowerStar 3kW (a 24V and a 48W) so paralleling them was easy (held my breathe for a risk-all-lose-all-or-win-all moment when duplexing the output). Still not satisfied, I gave it some thought for a whole afternoon and evening then came up with an idea which might work. I had spoken with Chris81964 earlier in the day and his home installation gave me an idea - go 24V all the way! I grouped the batteries (which had undergone alternate day equalisation for 10 days; pretty hard on them as I was literally boiling them) into roughly matching pairs in performance and ended up with 4 strings. Drew up an unusual cable path to achieve perfect balance and spent an evening cutting and crimping them into matching lengths (GeorgeD1's equal-link-cable variant would have worked just as well but I'd need lots more 50mm cable or really long and thick copper busbars). Also changed the inverter and CC cables to shorter, thicker cables as I'd be running twice the current thus risking roughly 4x the heating and 4x the voltage drop for high current draws. The logic? The individual pairs are balance-matched and paralleled with other balance-matched pairs. Each string has equal current draw with the others. The strongest one determines the voltage and keeps the weaker ones from lagging behind. In heavy draw, the strongest takes a bit of a harder hit (but that's why it's the leader). In series, the weakest ones would have given all they had first and subsequently become power pockets or holes in the bank. They'd simply die off after a few cycles and become fast-charging and fast-discharging cells thereafter (having lost capacity) and force the others to gradually become like them. Or become them. I have posted this to feed the body of knowledge as well as welcome contributions from other members in the house. PS: The reason I have a 24V inverter as a backup is, if a battery or two were to fail (and they eventually will at the end of their service life), a 24V system is the natural devolution of a 48V system. That would buy enough time to replace whatever needs replacing. And, should the main inverter fail instead, I'd still have an inverter to use. 2 Likes |

I like the idea of having a backup 24v inverter system when your main inverter is nominal 48v - for me it happened entirely by chance as I experimented, learned hard and expensive lessons and traded up in battery and inverter quality while keeping the still useful parts from old installations. Is it possible you share a picture or rough schematic of your current design? Did you get improved performance with this new design over the previous? What brand were these 12v FLA batteries? - my first experience with FLA was Mercury 12v 220ah - they came brand new but with very poor performance ab-initio - my hydrometer test showed low SGs all round so I had them taken back to service center and refilled with a proper SG electrolyte mix + a long equalization charge and they did pretty well after that - used them for a year before I sold them off and upgraded yet again. My current bank of 8 pieces 6v L16s also showed one weak battery during the rainy months with poor solar yield - I used a cheapo manual charger to boil/equalize the guy and it has since come back to life with SG & voltage similar to others though slightly lower - I do believe the key to battery recovery is to isolate the faulty battery/ies & charge/equalize it/them individually with SG & voltage measurements and then load tests to assess recovery - of course you have to detect the problem early for best results.

Re: Solar Energy, A Complement To FTA by Saipro(m): 2:53pm On Aug 15, 2017 |
NiyiOmoIyunade: Yeah, boiling was done in clusters where possible (the 48V bank) and individually for 2 of them (one had 3 cells down and the other had two cells going down; difficult to equalize with others). Modified a cheap manual charger to become a battery killer and and boiled under supervision. 2 Likes |

efuro: I don't know anyone who has come here seeking knowledge and has left empty handed. Its just that of late we have seen less DIY people and more of people who just want their system to just "work" without putting in the needed time to make it work. DIY is not for everyone and it is not easy, if it were everyone would be doing it. It takes time patience and lots of learning which most are not ready to do. What people do here nowadays is problem dump. Dump their solar problems here and expect people to fix them often time they provide very little information. Its hard enough trouble shooting a problem from post from a forum. whats worse is trouble shooting without little to work with. In most cases the best thing for some persons is to seek professional assistance. If you are not ready to read and learn and get your hands dirty. DIY is not for you. 8 Likes |
