ceaser: Yup and basically less/same price to that of a 200Ah lead acid, yet this will give better performance. Isn't that a good deal ![]() 4 Likes |

ceaser: I actually mean "dangerous dangerous", but not in the way many think. Lead acid and our inverters have been married from factory. Most inverters will cut off from battery around 10V. Your battery's SOC is still substantial at 10V if you have some reasonable load on. So, the arrangement of your inverter cutting off at 10V suits the Lead acid battery very well. When your inverter cuts off your lead acid battery is unlikely to be substantially at risk of destruction. The situation is different with Lithium Battery. Your Lithium battery's voltage will not drop like that of lead acid. So, when you have used 80/90% of your Lithium battery capacity, your voltage is still well above your inverter cut off voltage. So, before you inverter cuts off at 10V, your lithium battery will be at or precariously close to dangerous levels. However, if you have a good BMS, it will cut off your battery before it gets to this dangerous level. But, some BMS have a reset button which allows you to reset your BMS and still fire your battery a little more. By this time, your battery may actually be on its deathbed. I therefore opined that you should invest in a battery monitoring system if you are putting money on Lithium. If you have batteries that has BMS that can talk to you, another monitor may be redundant, but if your BMS is deaf and dumb, it is advisable to have a monitoring device to monitor your discharge rate, your voltage and your DoD. Lithium battery is less forgiving of abuse than lead acid batteries. That is the (potential) danger. 1 Like |

Simply put, in order to use LifePO4, I must change my inverter to one with custom settings, that I can change float, bulk and Low voltage cut off.. That's why I learnt from several YouTube videos, what if you don't have time to babysit, battery monitoring is not an option ![]() |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 10:45am On Mar 21, 2020 |
Dam5reey: Yeah that's right, I personally think folks should not be using an unmanageable inverter in the first place, even for lead acid batteries. As a network professional, the thought of using an unmanageable network equipment such as a switch will only create a doomsday in near future. 1 Like |

Dam5reey: Could you list any of the chinese /indian inverters...that are lithium batt friendly? |
Re: Solar Energy, A Complement To FTA by adrusa: 11:14am On Mar 21, 2020 |
Dam5reey: YES! You must be able to set charge voltage and current on your inverter/charge controller. You must also able to disable automatic equalization or at least be able to set the voltage. |

earthrealm: The bluegate 3.5kva/24v am using has custom setting for Bulk, float, low battery and End of discharge voltage. It's gud in charging my tubular battery, i believe it will likewise be gud for lithium batteries |

Has anyone here come across/used 250w Flames solar panels ? |
Re: Solar Energy, A Complement To FTA by Dam5reey(m): 11:48am On Mar 21, 2020 |
earthrealm: To me it's simple, any inverter that has custom settings to set Bulk, Float, and LVD, and also disable equalization, will do the job.. you can even bypass the BMS by connecting directly to Battery terminals. Since your charger will handle Overcharge and Discharge voltage. I plan to get this: and try out the 24V 200AH LifePO4. https://a.aliexpress.com/_B05a7N The seller sent me the Manual in PDF format, it will do just fine.. 2 Likes |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 3:54pm On Mar 21, 2020 |
Dam5reey: Don't do that, your inverter will be working with cumulative voltage while the BMS will work with individual cell voltage. The latter is more important and critical. I will also suggest you don't go for that inverter (the max array is 1kw), a 3kva felicity hybrid is better. Overall if you can, go for MPP or Axpert product 1 Like |
Re: Solar Energy, A Complement To FTA by Dam5reey(m): 6:51pm On Mar 21, 2020 |
ojeysky: I understand what you meant, The batteries will only have different voltages when you use Higher current, I'm only discharging at 10amp maximum Even active balancer are useless when you have low charge and discharging rate, also when the batteries are of the same age and are still new. BmS and active balancer are only useful for Ageing LifePO4, like the BYD used one.. The 1KW is overkill already for my application, I'm not planning to run AC on it anytime soon.. My total consumption is less than 2kwh daily. I'm switching to Energy efficient devices, Instead of using home theater I opt for 30watts Bluetooth speakers ![]() ![]() Sound Core motion + |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 8:39pm On Mar 21, 2020 |
Dam5reey: Hmm... that isn't accurate, I can agree with active balancer but not for BMS. They are useful for any age of battery. While there is a chance that well matched cells (with max 0.03 difference) will usually not differ significantly during charge and discharge, the BMS also will continue to contribute to that. The other thing is that yes you may be able to get away with the bottom voltage through your inverter but setting a safe top voltage without a BMS in place to prevent overcharge will be risky. As to the inverter, it's an axpert clone just like felicity and if the same (or less) amount will get you a higher spec why not. You never can tell what the future brings with your consumption. If there is no extra cost for getting more value for money, one naturally should go for it. |

Re: Solar Energy, A Complement To FTA by Dam5reey(m): 9:44pm On Mar 21, 2020 |
ojeysky: The inverter will do that as well, the essence of BMS is to automatically disconnect as a set voltages, if your inverter does that for your then there is no point.. it is more risky when your BMS and Inverter does not communicate with each other. I'm not saying don't use BMS, For me it will be connected to batteries, but bypassed for charge and discharge. |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 9:57pm On Mar 21, 2020 |
Dam5reey: Hmmm... Will look forward to your experience on this...my gut tells me that the inverter won't be optimal with this compared to a BMS. it is more risky when your BMS and Inverter does not communicate with each other. Hmm....I don't think so, yes it will be good to have a BMS that interacts with inverter but I don't think lack of that is more risky than not having BMS in place.
Not sure what use a BMS will then be if you already bypass it. Ultimately it's a choice, but will be good to know if you have this set-up already, if not do share your experience after a few months of usage. |
