WILUG:1. YES. There is no problem mixing different battery pack in parallel provided they have the same chemistry and voltage. LFP is LFP and gets along with its family regardless of relationship (manufacturer). 2. YES. You can use pack with different AH ratings but there are a few things to prepare for, mostly how the EndAmps/Tail current is handled which is what takes the charger from Absorb/bulk mode to Float. If you have identical bms, it's much easier but if you mix bms, trying to match all settings and functions might be difficult. Again, you're better off getting matched and batched grade A cells with Factory Test Reports that shows the Full Test Cycle. That way you can be certain that the cells will have an identical IR throughout the working voltage range. 3. Even after a year. You can use 3 Likes |

Re: Solar Energy, A Complement To FTA by Xanderone: 3:45am On May 23 |
So I don't wanna make another terrible error, this time with a central stabilizer. I may need to get one anytime as I was able to secure a prepaid meter that has for a while been installed but not used cos it had some error codes which made me unable to load a key change code and credit. The issue has been resolved. So I discovered the voltage supply is a terrible regular 160v and seldom 180v. I did some searches and saw Prag, A&E dunamis models (10kva) and another funny name like this (Jor-El) π as in Karl Kent name. Anyways experienced users should kindly provide some info. β’ Which models are tested and trusted? Few days ago, I pulled out about 4 units from storage that I last used about 6 years ago and realised they can't seem to handle the 160v input. β’ How durable are these things? I read one of the reviews on Konga where a buyer cursed that the Jor-El he bought didn't last more than 6 months and it stopped working. β’ How good are they in protecting appliances? My appliances have been safest on solar for many years now but foraging back into NEPA means I may be courting damage to these appliances from overvoltages, undervoltages and fluctuations. β’ Any other questions that I may have missed but that experienced users know will also be welcome. Thanks as always. NB: I assume 10kva may suffice for loads which I anticipate may max to around 4kva with future upgrades/addition of appliances. I also do not intend to hook my inverter AC charging unit to anything NEPA under any conditions whatsoever. It should continue to use the solar charging abeg, to avoid stories that touch. I've however thought about installing an automatic rapid changeover switch to handle the change from inverter to NEPA whenever the latter gets the seizure brain waves to provide supply.

Xanderone: Stavol by Matsunaga is a better make. Go to JiJidotng and search for Stavol AVR or Matsunaga. They do make awesome servo AVR I saw a Bluegate 20kva there too, that stabilizer can boost 130v to 220v. 1 Like 1 Share

The repairer has fixed the Felicity controller and he gave me 1kva inverter to be using first pending when he finished fixing my inverter, I have installed everything myself but I noticed this on my battery, the acid level on my battery gauge has gone down just for this few days I didn't charge the battery, I want to know if I can top up with distilled water at this level osayuwamwen:

I will share with you my personal experience with these servo stabs. THEY WORK AT THE BEGINING BUT WILL GRADUALLY FAIL. Yes, they will fail because the movable parts on that huge toroidal coil will interact with the dusts that are settling on the spindle and coil. After a while, the dust might create a short circuit on the surface of the coil and then the stab will start dropping breaker or fuse due to the explosions from the short-circuit. I have had this issue with more than four different brands, same issue ooo. Service center guys will try to file off the affected surface and it will work well only for the fault to return after a while. I eventually stopped taking stuff to the service centers and started opening them up first damn the warrantee, see what went wrong and decide if I should go through the hassle of lifting heavy stabs to service center every now and then. So during my quest, I discovered that DUST IS THE WORSE ENEMY OF A SERVO STAB. Then I switched to a relay version and I have been using it for more than 5 years and counting without a single issue. My Advice: If you must do a servo stab, make sure it's dust proof. Xanderone: 5 Likes 1 Share |

[quote author=osayuwamwen post=130096147][/quote] no need to top up, just charge it fully and if possible carry out equalization charge on it |

jonescosmos: I have been using a servo AVR for 8 years now. Yeah, dust is an issue, as long as the coil is great, you are good to go. Mine was even bought used. I don't think I'll get the regulation I get from this from a normal relay AVR as this beast can handle crazy NEPA low voltage (which I hardly use). A relay AVR will truly struggle to do what it can do. 3 Likes 1 Share |

mctfopt: Thanks. Noted Edited: The offers available on that website are all used o, both Stavos and Matsunaga. I didn't come across a new one.

Re: Solar Energy, A Complement To FTA by Xanderone: 10:45am On May 23 |
jonescosmos: Thanks for the info. Dustproofing an appliance like that may require totally shrouding it in some form of metallic or plastic case. And being a resistive appliance, it will require adequate ventilation to get rid of the heat that accompanies use. That precludes attempt to dustproof it. Also the manufacturers probably are aware of that achilles heel of their servo stabs but are probably not worried cos the dust issue is only a problem in dusty subsaharan environment which constitutes a small part of their customer base. So that brings us to the relay version as the available type. Are there any downsides of the relay version compared to servo types? I don't think I have seen relay types with 10kva capacity or more. From your experience which relay type stabilisers would you recommend? |
Re: Solar Energy, A Complement To FTA by mctfopt: 11:20am On May 23 |
Xanderone: New ones are available. Stavol is produced by Matsunaga.
