quest4s: Does the DC voltage of an inverter determine the efficiency of the sine wave of an inverter? When you say it supplies more power, what exactly do you mean by that? Is the power here related to the duration of the backup? Because if it is, it only depends on the AH rating of the battery in play. 1 Like |

quest4s: Both supply same power. If it's from same manufacturer and of same spec except for battery voltage, then both would produce same waveform. - 24v inverter will use 2 12v battery while a 48v inverter will use 4 of such battery. -current sharing is a problem for 24v battery if you decide to use 4 battery whereas it won't be for a 48v inverter. For the 24v setup, one string will do more work than the other except you use busbar at every voltage point reference (0v, 12v and 24v). -for a 24v setup, if using busbar you only have to bother about balancing only two block of battery whereas in a 48v setup, you're balancing 4 blocks of 12v battery. -like earlier noted for a 2.5kva 24v is better in cost management. Don't think of only the initial setup, consider replacement cost. 2 vs 4 battery -if you want to go solar, asumiing a single charge controller of 60A, a 48v system will be able to handle twice the amount of solar panel of a 24v system. -if you intern to go lithium in future, 48v is best. Most premium brand, provide ideal cost savings in their 48v setup. From experience, below 1.5kva 12v setup is ideal, below 3kva 24v and up to 6kva 48v. If cost is not a challenge, a 48v system is the best for the capacity you envisage. Reason: lead acid battery perform better at moderate discharge and charge rate. If the rate is too high, capacity reduces. For instance, a 200AH battery may only be 150AH if current is drawn at 40A, 210AH if drawn at 1A, and 200AH if drawn at 10A dependent on the specification. 6 Likes 1 Share |

quest4s: Do 48v if you can afford it. It is less stressful for your system compared to 12v or 24v. It also allows you to use more solar panels on the same charge controller. Your wires will not be as hot and your contacts will not suffer so much burns from arc current. The only disadvantage is the minimum number of batteries required which is 4. You can minimize the cost by going for lower capacity batteries like 100AH. 2 Likes |

quest4s:The 24v or 48v talks about the voltage needed before the inverter can work NOT necessarily the CAPACITY of the inverter as per its ability to carry load or supply power to your appliances. Also the sine wave is NOT "purer" based on voltage!!!!! 1 Like |

hancock: Yes o.... infact having learnt that I can introduce new battery at any time without negative effect, I am hoping I to get another 5.4kwh by end of the year[1] so I can add to my existing 5.4kwh. The stuff is small but mighty...the way it withstand temporary current demand spikes is amazing! Cheers! [1] Assuming the performance of current one continue as it's currently experienced. |

I have a solar power system of 3KVA 12 volt inverter and 2 pieces 200AH battery. I use it to power only 1 chest freezer of 169 watt 1.2A but the issue is that the battery gets drained and drop to around 10.8 whenever the sun starts setting (around 4pm). I have a feeling the battery is not good or is this normal. The set up was done about 3 months ago and initially it last over the night till when the sun begins to rise but recently, the battery gets drained so fast. Pls advise |

abbeyforex: you need to break it down for easy review. give more info. for now batr - 400a x 12 = 4,800w load - 169w x 14hrs at least = 2,366w i am suspecting ur solar panels or setup is not adequate to charge ur battery to full that is why on d first day the batr power was able to run overnight so let's have ur solar setup info ok 1 Like |

abbeyforex: Your information is lean. Btw, does your freezer run 24/7? What voltage did your battery hit before it starts charging in the morning? Did it get there float durning the day before sun down? |
| Re: Solar Energy, A Complement To FTA by unicmarket: 7:28am On Feb 02, 2020 |
abbeyforex: I think I get your point This issue can be traced to your battery(probably are bad) or its that your Inverter as destroyed them; by consistent over discharging the battery, and in long term as destroyed the battery, a good Inverter should not discharge a battery below 10.5- 11v, so as not to use up the batteries to 0 level for a longer life span. Because once the sun goes down, your battery drops to about 10.8v, this may show you immediately that your battery cells could have been tampered with. What to look out for 1. The battery (orginal?) 2. The solar charge controller( could it be that it’s overcharging the battery; which could I turn damage the cells) 3. The Inverter May have been using up the battery cells to 0point and in turn damaged the cells I would advice you contact your installer; if you haven’t. But you could chat me up on whatsapp too ; let’s see how you can fix it. At my signature 3 Likes |

abbeyforex: First of all, your batteries are bad, they suffered undercharge for a long time and gave up. Secondly the daily yield from your solar array has reduced drastically as a result of dust cover. that's what destroyed the batteries. you need to wash them clean and replace your batteries. you also need to clean your panels routinely during the dry season, at least once in a month. 1 Like |

abbeyforex: 8 of 150W is 1200W. Your total generation will be 2400 to 4800W a day depending on ambient temperature and solar insolation. Assuming a freezer of 167W is on 2/3 of the time in a 24hr runtime = 2,671W Asume inverter self consumption of 50W: total in a 24hr day = 1200W Asume average of 50W for other opptunistic load (it may even be more than the 50W): total in a day = 1200W. If you sum up usage, you'll see that generation is below consumption. At the initial stage of setup, battery was providing the balance, but now that has been depleted. Note: This calculation is based on information provided. 3 Likes |

abbeyforex: good points made so far. in addition, kindly confirm the type of charge controller you have, and state your panel config. your battery is prolly damaged from being drained too much.i believe u allowed your freezer run 24/7 initially. get a timer socket and only run the freezer for 8hrs max daily, since ur inverter is 12v, i wonder the type of cc u have, that u were able to put 1200w panels on it. too many unknowns/variables in this case.. what i would advice you do is state all your loads , their wattages and run times, then people can suggest a suitable design for you 3 Likes |

A good system design considers: 1) Load 2) Backup time (discharging) 3) Charging All have been covered in this thread and on many sites online. Its always good to have a little knowledge of what you want to buy or repair. Invest in tools. Read and learn, even if you don't need it at this time; even if you want to contract out your installation. Your installer may not be too knowledgeable and spoil your hardware. You may end up buying wrong parts due to wrong diagnosis. The error may not show up immediately. I've heard of cars burnt few days after a visit to an auto electrician. I've seen panels connected or oriented wrongly. All this could have been solved if the onwers had little knowledge and supervised work themselves. You don't need to be an engineer to know the basics; you don't need to be a lawyer to know laws. Having a little knowledge about everything pays. 4 Likes |

Ojaysport: It really depends on what you need or what your pocket can afford. Mine is a 24v 5.4kw at 450k. There sure other top brands that costs more....those got way more better packaging, logging, bells and whistles but mine works as I hoped for and that's all that matters. |
