  1. Hi Guys, Good day As per subject I need the actual picture of the MPPT board & part number of the "MPPT module" present in the ALFA-M3000-24 Solar Hybrid Inverter. The brand name is NS but it is very similar to Voltronic or Axpert models I have the picture of the board of the inverter with the missing MPPT module. I need the picture to procure the MPPT module. Please see attachment. Thanks
  2. While we are at the topic, Can someone post a picture of MPPT Module for ALFA-M3000-24 please? I need to procure it but I do not have the MPPT module anymore. please note that I am requesting picture of the MPPT module of the M-series AFA-M3000-24. The real picture is needed so I can send it to my seller in China to procure it. Thanks so much.
  3. @Mr T Here you go. Capacitor Details: 475K 350VAC See Photo 6.jpg Zoom it a little bit and you will find the value crystal clear. I hope I am not too late for the reply.
  4. @Chris Hobson You are probably right. I should look for deep cycle batteries. They are available but much expensive.
  5. @plonkster Thanks interesting finding @Chris Hobson @plonkster Its a 3-step charger so I understand the terms "Bulk Charging voltage" and "Floating charging voltage". Can you guys please explain to me a little bit the following terms to me? Back to discharge voltage Back to grid voltage Battery cut-off voltage Kind of confused about what these terms actually mean. My new settings look like this now: Do I also need to set battery type to Flooded or User? Thanks for your helpful response. Awais
  6. @Chris Hobson @plonkster Thanks for your useful input. I think that is what I was looking for. I also think that the unit stops charging the batteries too quickly and switches to floating charge in about 10 minutes which is an incorrect behavior. I do not have any solar panels at the moment and I use only AC for charging. I will try the suggested Bulks settings as soon as AC grid comes back on. @Chris Hobson Phoenix is a catchy name, I think its all that is :). English although widely understood and used in our country, 90% truck drivers (who are the largest consumers of these batteries) are not literate enough to understand that! I think its easy on the tongue and seems a catchy name for most of those people. LOL
  7. @Chris Hobson @plonkster @The Terrible Triplett I have these settings options. Please help me configure the right options for my batteries. The batteries spec is also attached.
  8. @Chris Hobson Yes I agree. Its probably a Voltronic clone. See attached images of the UPS. I don't discharge the batteries as I don't have any large load at the moment (2fans 60watt each and two tube lights 60watt max) . However, i think the UPS only float-charges the batteries and does not do a bulk charge long enough to provide them enough juice for the next load-shedding (which is one hour only). So after 3-4 load shedding(s) one hour each every 4 hours, decreases the juice of the batteries. If the batteries were being charged by the UPS (and no float-charged) this would not have been the case. If I could set the battery to user, what should be correct settings for the batteries? Please see attached images and advise Awais
  9. Hi guys. Problem: The UPS seems to charge the batteries too quickly. Detail: This is a 3KVA Alfa P-3000/24 UPS with two 12Volt DC batteries (a total of 24 volts). If batteries are discharged to 30-35% (on load voltage 20.x Volts, UPS reading 22.26Volts), it seems to charge the batteries in almost about 10 minutes (voltmeter:24.5 Volts, UPS reading: 27.xVolts) Batteries are "Lead Acid water maintainable batteries" but the settings in the UPS are for AGM as default. I dont understand the difference and need advice. The only other options are Flooded or User. Questions/Suspicion: Obviously this cannot be right. Furthermore, even after having the batteries on AC charge via the UPS for more than 4 hours, each subsequent backup keeps on reducing until I need to charge the batteries using a separate battery charger or having them recharged by a battery guy. I want to understand what is wrong and whether its the settings that need to corrected or something else? I recently installed fresh batteries since I have was having problems with the previous ones. Background: I had problem with previous batteries when my UPS experienced a short circuit and needed to be repaired. After repair, It was found that cells of both of my batteries were shorted. So i installed new batteries and since then I am facing the problem as described above. Screenshots: I have attached the screenshots from WatchPower (the software that comes with CD) Kindly help resolve the issue and help me make/implment the right software/hardware solution. Awais
  10. Thank for your reply @plonkster. Really appreciate the detailed explanation. I am trying to establish if its a fault in UPS or battery so that I can fix that problem. Right now I am unsure as to what exactly is problematic. Personally, in my humble opinion, If the UPS thinks batter is charged, it will switch to floating charge... and if the battery has a problem, it will get charged (or at least appear) to get charged immediately, attaining a voltage level that puts the UPS into an illusion that battery is fully charged. I need a second expert opinion so that I can work towards a solution. Thanks
  11. Question: How long should it take for 3kva ups to charge a 12V+12V batteries from 70% to 100%?
  12. Turns out, one of the cells in one of the 12Voolt batteries was shorted. I have got that cell removed and a new one installed. Still testing. will upload and share the results. I just want to make sure that UPS is supplying correct amount of voltage and current and there is no other problem in the UPS itself.
  13. Here are the screenshots 1. Datasheet 2. Device Parameters 3. Graphs for various stuff. Please take into consideration and help me establish the battery's health as well as the UPS health. Thanks Awais
  14. One small problem is that the batteries are getting charged very quickly and are not giving a backup of more than 1 hour on: 1. 3 tube lights of 60 watt each 2. 2 ceiling fans of 60-100watts This was noticed after charging the batteries for 3 hours straight (note: floating charge because it charged the batteries to full in 30 minutes). Furthermore, batteries are getting charged on a floating voltage as the battery charge indicator is full. Its gets full in almost 30 minutes. Please note that I have lead acid batteries which are water-maintainable and I had them recharged by a battery guy on a higher current (They do this because they say that UPS is not capable to charge a dead battery, the charge must be at least 50 percent or higher for UPS to pick it up). Does this mean that batteries are faulty or does this mean that they were charged to full? The batteries details are: 1. Battery type is set to AGM in software 2. Battery Bulk charging maximum voltage set to 28.2 3. Max AC charging current : 30Amp 4. Battery : Phoenix XP 200 Plus which according to this chart http://phoenixbattery.com.pk/product.php is between 120AH to 150AH. 5. Battery voltage in series for two batteries (12VDC each) when charging: 25.2 - 26V (taken via digital multimeter) 6. Battery voltage in series for two batteries (12VDC each) when dis-charging after 3 hr charge : 24.2 V DC I need to help figure out if the batteries are faulty (they get charged and discharged too quickly?) Also, need to figure out if its the inverter problem so that I can figure it our myself or get it repaired whichever option is cheaper... Thanks Awais
  15. Hi I was not able to solve problem on my own but I reached out to a local repair shop who fixed the problem in an hour! LOL I wish I had gotten a hold of ALFA manual sooner maybe could have have saved me a couple of bucks LOL But this manual will surely come in handy when I run into another problem again. So thank you so much! The technician told me that two resistors were busted near the bridge rectifier. Further more, there was a diode busted in the output section and a couple of transistors in the output section on the heat sink. I am not sure If he was right about what he said (he could be exaggerating the problem to justify the money he took to solve the problem).
