gtech2sure: There are some basic assumptions here that will cause serious problem. 1. I didn't see depth of discharge (DoD) here. For lead-acid battery, you don't have all the capacity available, may be about 50% at best. Some may say 80%, but depending on your load and your cut-out voltage, your inverter will cut off well before you can get to 80% of DoD. So, in calculating your AH need, you must double the result from your calculation. If you need 200AH, get 400AH. 2. I also didn't see "efficiency factors" here. In moving from DC to AC in an inverter, some power will be lost. It is usual to give about 10% of your power to this loss. Also, solar panels also have efficiency factor. This must also be taken into consideration. A 1KW array will not give you 1KW in an hour, it will be less. In addition, the sun is not likely to be full blast for full 5 hours in a day. So, some power will also be lost during cloud passes. Finally, batteries don't convert all available energy to storage during charging. Some of the energy are lost as heat. So, in making this kind of calculations, there is a need to make allowances for these imperfections in electronics. 4 Likes |

The cells in one 12v battery should not be varying much between OK and FAIR per their SG readings. They should all read very similar within a narrow SG band. Might be time to get a temp compensated hydrometer with numeric readings. Did the electrolyte in the batteries come from thesame source and thesame batch? Did you at any time have a spill or water loss wnd then topped off with additional electrolyte? What is your equalize voltage per 12v? You should be at or above 15v for any meaningful equalization. It might also be time to break the bank and charge and equalize per 12v standalone. Malevonent: 1 Like 1 Share |

If you are still undecided here is a piece of advice, going lithium from lead acid battery is like upgrading from a horse ride to an electric vehicle. ![]() 2 Likes 1 Share |

40a Suoer 12V smart charger for sale. Reason for sale: Bulk charging and float voltage higher than my battery spec. I bought it for 18k on Jumia and it goes for as high as 23k on Jiji but if anyone will find it useful I'm willing to sell it for 12k. If interested, send a WhatsApp message.

mctfopt: It's like you just experienced some new stuff about lithium.....my battery was charging at 48A yesterday with a smile. Lifepo4 is cool, even if what I get from it is 5 years considering the performance I am getting I will still be fulfilled. Planning a DYI Lifepo4 soon to increase my battery bank capacity. 3 Likes |

adrusa: The way I compare it. 100% DOD lithium is 50% lead acid and 80% dod lithium is 30% lead acid |

ojeysky: That is one of the advantages, the ability to charge at supersonic speed and high current without fear of damage to the batteries. Lithium is just the future. |
