All this talk about CCs, hybrids, spare boards and all ... I have a few clients with 24V 3kW Must inverters with bad chargers. Two with bad inverter sides on PowerStar 48V inverters (seem immune to charger going bad on account of using desulphators) Anyone with spare boards and cost implications? Anyone knowing how to fix/recalibrate these devices? |

Does anyone have transformerless inverter of capacity between 1500 to 2000VA, with AC charger and Pure Sine Wave output for sale? |
Re: Solar Energy, A Complement To FTA by Lovelynife(m): 8:09am On Nov 09, 2020 |
what are the cons and pros of transformerless inverter?
which is better out of the two? Transformer and transformerless inverter?

Re: Solar Energy, A Complement To FTA by Penuelseun(m): 8:56am On Nov 09, 2020 |
Lovelynife:They all have transformers in them, just that they are different types (iron core, ferrite core, toroidal), they all have efficiency ratings which influences the no load consumption of the inverters they work in 2 Likes |
Re: Solar Energy, A Complement To FTA by Penuelseun(m): 9:00am On Nov 09, 2020 |
Iron core transformers are rugged but consumes more power compared to the other ones, they are also heavier and bigger. Ferrite core transformers are smaller, lighter and energy saving but can't handle surge current like iron core transformers 1 Like |

Felicity Lithium users. Help needed please!!! 1) How does one implement a reliable low voltage disconnect at 49.5v? The site I just inherited, the felicity inverter has a maximum permissible low voltage cutoff at 48v - I need to raise the cutoff voltage to 49.5v approximating 80% DoD. I am looking for suggestions for a reliable low voltage disconnect mechanism please - I guess this will be an external/add-on device. 2) What is an ideal float voltage setting for the Felicity Lithium? The manual is silent and only specifies 57.6v as the charge voltage. 3) Internally how many cells are in series? I suspect 16 cells? If there are 16 cells then perhaps 57.6v for the pack or 3.6v per cell is very very highly charged and not ideal for the long term? |

Re: Solar Energy, A Complement To FTA by IYGEAL(m): 11:08am On Nov 09, 2020 |
Penuelseun: I think this is a very good explanation of the models. In a nutshell, if one's max load is 500w, it's wise to go for about 1000VA with the so-called transformerless Inverters. How about the other types you mentioned though? |
Re: Solar Energy, A Complement To FTA by Valto(m): 11:17am On Nov 09, 2020 |
IYGEAL:icellpower 12V 1.5KVA pure sine wave inverter, though with transformer, but idle consumption is around 10 to 12W....comes with 20A charger. battery settings, charging parameters, input and output settings are all customizable. i have a very clean used one for sale @affordable price. |
Re: Solar Energy, A Complement To FTA by Lovelynife(m): 11:28am On Nov 09, 2020 |
Penuelseun:Thanks. any recommendations of the type with low/no load consumption/idle consumption that you can recommend. Thinking of schneider homaya hybrid before(but av not seen good review) but I av in mind Afripower,microtec or icepower |

NiyiOmoIyunade: Let's see if I don't get banned again by NL bot 1. In my case, I put the lvd on highest possible on my inverter then make sure battery never gets there through yet of Sonoff/nodered/BMV combo to turn off all power guzzlers at various SOC. The last one (fridge) goes off at 15% SOC 2. I won't float above 54.2 3. It's LFP so it's 16cells (multiple or individually), i will charge up to 3.5v max(in situation where grabbing the sun juice within shortest period of time is important). However ideally I will do 3.45v Edit: to add response on 1 |

Re: Solar Energy, A Complement To FTA by adrusa: 12:54pm On Nov 09, 2020 |
NiyiOmoIyunade: Lithium are not supposed to float. It is bulk and then stop. The idea of a float charge is to account for lead acid self discharge which is minimal for Lithium. The recommendation is to set your bulk, absorption, float and equalization voltages at the same value which depends on how you want to drive your battery. I set everything to 55V for my system 16s batteries. You set equalization voltage at float as double security since equalization will rapidly destroy lithium. You must disable equalization on your charger also. Felicity has 16 cells. I use node red and a contactor to cut off my inverter on lithium at 50V. I have not really looked into hardware LVD. Others may advise. |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 1:57pm On Nov 09, 2020 |
adrusa: I think that's a typo, as you right indicated later, please do not equalise an LFP, a lot could go wrong doing that unless you want to do it for just a few minutes because equalisation will try to maintain the voltage point even when the battery does not needs it. I have a feeling it was the mistake I made with my MPP board that I lost initially. |

Lovelynife:Don't try microtech if your battery bank is low as it is a power guzzler, I personally use ceepro inverter, no load consumption is 8w, albeit no charger 1 Like

Re: Solar Energy, A Complement To FTA by ceaser: 3:46pm On Nov 09, 2020 |
NiyiOmoIyunade: This is one set up that can be used, if the inverter has that kind of switch. However it will require prying out that switch and constructing an external lead out to connect to the battery protector. Then the switch can be replaced back. The line-out from the inverter is connected to the two terminals of the original switch of the inverter. The charge-discharge controller has adjustable low voltage discharge and high voltage reconnect values, a battery input point and relay control output. The battery input connects to the battery terminals. The relay input connects to the contactor (first picture) or Solid State Relay SSR (second picture). Once the battery controller senses the preset voltages, it activates the relay which in turn turns on or off the inverter as the case may be. For the battery controller in the first picture, the low voltage must have remained at the set value for six seconds to qualify to activate a disconnect. Anything less than 6 seconds, it will be sensed as the typical transient battery voltage drop that occurs with powering on high surge devices with the inverter, something usually more common with lead acid. I'm not sure that 6 seconds thingy occurs with the charger-discharger controller in the second picture but it has a few more features than the first. But I guess the inverter in use in that location will likely be the soft touch switch type in which case this arrangement might be challenging.

Folks, what wire guage would you suggest is suitable for 48v system likely to have 3s3p 320 watts panel travelling a distance of 30 feet (approx 10 meters). 6mm wire? |
Re: Solar Energy, A Complement To FTA by saint2ace(m): 5:48pm On Nov 09, 2020 |
IYGEAL: It's the X4 Echo Series.... |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 5:55pm On Nov 09, 2020 |
ceaser: 6mm would do but I used 10mm when I had similar set-up though with 270w but current it carried is close to yours. Would suggest you use 10mm if you've got some budget |
Re: Solar Energy, A Complement To FTA by ceaser: 6:46pm On Nov 09, 2020 |
ojeysky: Thanks. 10 mm it is then. Especially since it may later need adding more strings of panels since the starting controller is going to be 100 amp SCC. |
Re: Solar Energy, A Complement To FTA by IYGEAL(m): 6:53pm On Nov 09, 2020 |
saint2ace: Okay. The setup currently has Luminous 850VA. I think they are basically similar. |

Penuelseun: Does this Ceepro have up to 1000Watts capacity? |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 7:00pm On Nov 09, 2020 |
Please where can I get either module? They look like they would fit my need. I am wary of the Victron battery protect since it disconnects the DC side of things and appears to work safely in only one direction - the literature indicates it may burn up if the direction of current reverses. ceaser: |
Re: Solar Energy, A Complement To FTA by obinna37(m): 7:15pm On Nov 09, 2020 |
Penuelseun:pls link where you buy it |
Re: Solar Energy, A Complement To FTA by adrusa: 7:22pm On Nov 09, 2020 |
ojeysky: It is a double protection. Set equalization voltage to float voltage and then disable equalization. Setting equalization voltage to float protects your battery if equalization is mistakenly enabled either by unsteady finger or any such other mistakes. 1 Like |
