Every DIYer or pro installer must have a multimeter capable of DC voltage measurements at the minimum - if you can measure DC amps with a clamp then all the better. With a cheap mulitmeter, you can check battery and PV connections for voltage and correct DC polarity and avoid expensive or dangerous mistakes. Peterlove11: 2 Likes |

Please confirm that the coil in this contactor is actually rated 54VDC? In my testing the coil energised successfully even with 48VDC voltage applied. wilmaria14: |

Lovelynife: Most China made inverters.Icellpower inverters have such capabilities.vThe high end inverters too like Sorotec,Phocos etc |

I read this with some excitement as I have considered and experimented with mixing different battery types and chemistries together - when I maxed out budget on Pylontech, I considered mixing with Dyness batteries which had similar voltage profile but ultimately did not pursue this path - I have also considered mixing with the Felicity LifePO4. Lest people begin to apply this solution indiscriminately, I feel compelled to say it only appears to be working in your scenario because the two batteries being combined have fairly similar charge profiles - indeed the Lithium bank will charge and discharge first but that is about where the similarities end. If you are running a high C rate application (charging with large currents and discharging with large loads) you may find the Lead Acid bank being stressed more than they can handle (your charger will not suddenly throttle current when charging switches to the Lead Acid only and neither will the loads suddenly drop off when being supplied by the Lead Acid only) - for long term stability, you would be constrained to set your absorb voltage to slightly undercharge the Lithium bank (not get to 100% capacity) and possibly severely undercharge the lead acid battery since the critical absorb phase it needs cannot be properly done - incorporate a separate charger for the Lead Acid and you would potentially be overcharging the Lithium bank unless you have a mechanism to isolate the batteries while still keeping inverter and other charge sources powered up from DC. The way to run this safely is to isolate the two banks and dedicate isolated charging sources to each battery type - at the minimum there should be a dedicated inverter per battery bank and have them switch powering the loads with a suitable changeover arrangement - this can be done seamlessly. You can go a step further by setting your large loads to power off when the main battery hits LVD and this way use a much smaller inverter running smaller loads to get through the rest of the night. If you persist on the path of paralleling two different battery types, it is key to mention that at the point of combining them together, the two battery banks must be at thesame voltage at a minimum else you will surely see sparks fly as large and unregulated currents move from the higher voltage battery to the lower voltage battery - with Lithium batteries unregulated large currents can easily damage the battery contacts or permanently weld the internal protective relays all of which will cost you some inconvenience to fix. durodee: 2 Likes |

IYGEAL: Sorotec 24v 3.2kw, Valto listed one for sale a while ago, whaf i have now is 48v 3.2kw. @lovelynife, icell, sorotec, deye.... Even musf and felicity dont hv editable settings, but they have battery sel3ctor switch with diff voltages, which will also serve same function |
Re: Solar Energy, A Complement To FTA by IYGEAL(m): 7:30pm On Feb 18, 2021 |
earthrealm: Are those in turn editable? My little experience has shown some selectable battery type voltages are above the moderate limits for lithium batteries. So if they are not editable, they might not be very good in the long run, on the life span of LFP |

IYGEAL: The bolded isnt editable but fixed, i tot my advice was to the fellow having issues with his luminous and fla batteries.. However if the absorb voltage is slightly lower than the max voltage for lifepo4, some people say they hv been using it, no issues 1 Like |

earthrealm: Am using felicity hybrid with luminous 220ah wet cell batteries.......it's editable. Though Maximum voltage is 58.4v with equalization function. It works well for the batteries and charges very fast. Carries my whole flat, My freezer runs on it 24/7. Funnily I cook with it everyday(use 1.8kw infrared fast burner) 1 Like |

Good morning Team, does anyone has first hand user experience of Felicity GEL 200AH batteries.I spoke with the company and they claim their AGM GEL battery has one year warranty but we all know what most warranty in Nigeria means so I would like anyone who has usedvit for a first hand performance review.The data parameters on their data sheet looks good though. Any one has experience on above please?

Re: Solar Energy, A Complement To FTA by earthrealm(m): 7:34am On Feb 19, 2021 |
Peterlove11: Ok, true.. forgot felicity now have hybrids, it was the normal felicity that has same architecture as the old Must power star, i had in mind. However 58.4 is a bit low, 60v to 62v is best for equalization. IYGEAL: Growatt max Voc is 145v, i dont know if they have a high Voc variant |

When a standing fan begins to have a humming sound when on and only starts rotating when the blade is rotated, what needs to be repaired? The capacitor at the regulator part has been changed, the refusal to rotate still persist. All the fan repairers I used to see in the area seem to have disappeared. |

Peterlove11: It may look nice at first cooking with it, but it’s not the best. 1.8kw equipment and other may not be great though, you see most batteries we have over here in Nigeria at their Best comes with 2years warranty, not like over there that some batteries go as long as 5years, what does it tell us, we still some way to go I really advise you to as much as possible use minimal load on your inverters even though they are bigger. You may be able to manage it, what if you are not around and someone else puts on a lot more with your burner My experience with batteries is that, they don’t get bad just immediately you load them, it’s over time after an injury in the cells Minimise your usage, enjoy your Inverter for years and counting. Let’s never compare the way those guys outside load their inverters, they sure have warranty than ours, That’s a sign My little contribution ( for others) I greet bros! 2 Likes |

It has a good idle consumption on no load 7-15W And when like 70% or close to max. Load. 30W - 100W Or less IYGEAL: |

Re: Solar Energy, A Complement To FTA by adrusa: 11:47am On Feb 19, 2021 |
NiyiOmoIyunade: I align with this position. When I bought my lithium batteries, I still had my lead-acid bank which I estimated still had some good life remaining. What I did was to put the two banks on separate inverters, pv arrays and charge controllers and used some contactors and automations to switch from one inverter to the other. I had also thought about mixing them, especially for charging and I do that occasionally, but the different charging parameters is what prevented me from doing so. My lead-acid batteries are all also flooded cells that require occasional equalization. Equalizing lithium will kill them rapidly. So, it is better to keep the battery banks separate to prolong their useful lives. Combining them looks like a costly compromise. |

Good afternoon. Please, I want a solar structure as well as batteries for my household appliances( TV, Fans, bulbs, deep freezer, fridge and other minor appliances). But I want the fridge and freezer to be always on (24/7) while every other appliance can be average of 12 hours per day. I'm thinking 4 batteries of 12v200Ahr, 6 mono crystalline panels of 200W and an inverter of 12V2kva will do the job for me. Please, kindly advise on how to go about it because it's urgent. Thanks. |
