  1. Hi welcome. We need way more information to be able to assist. What battery chemistry and manufacturer. Do you have solar connected to the must inverter. What is your load profile. Send pictures of your installation and battery spesifications as well as inverter settings.
  2. 270 Over voltage disconnects is seriously problematic. Some information needed. Is there bms comms between inverter and battery? Why is Agm profile selected for Lfp battery? There is diffrent versions of S volt modules there is 15 cell and 16 cell. Hopefully yours is not 15 cell as that would explain the excessive Ovp count. Send a picture of the Svolt rating plate on the side of the module. With so many overvoltage disconnects the chances are good you have swollen cells that will need teplacement.
  3. That would be fine no problem there. There is 2 hard limits that must be respected Voc and Isc the latter for the Sunsynk 5kw inverter is 17A that won't be reached by the 445w panels. The only reason Sunsynk included the Isc rating is in the event of reverse polarity that could occur by mistake. That goes for all inverter Scc's. The Voc limit in my book is 450v. So overall yes North facing 8S1P and East facing 8S1P on both Mppt's will give you excellent solar production.
  4. There are many online scam companies lurking in the shadows some not even in the shadows. Now we have some form of protection identifying legitimate URL on the web. See below link, copy and paste the company URL and run the Detector. Scams vulnerability scanner: https://www.yima.org.za/
  5. @My Real Name Call the price there are guys interested Look at what you could discount from new batteries take into account you used them from early 2023.
  6. While we are on MC4 training here take a look at the video from Greenwood solutions trainer Veli for some very good pointers.
  7. It is very important to use this dedicated mc4 crimper below.
  8. Thanks @Scorp007for the correction didn't realize the batteries was "used" might help to read the add properly.
  9. I agree with @Virwatyou didn't really find the problem and still might have a loose connection within one of the mc4 connectors. It is now difficult to actually visually inspect each crimp once the mc4 connector contacts is pushed into the housing. There is a method to check for loose connections but you need to do it with caution. You will need a 20~30 amp dc fuse or 20~30 amp dc breaker to do this test. 1. Switch the Victron mppt off in the settings page under battery 2. Disconnect the pos and neg solar input wires from the Scc be cautious they don't touch together. 3. Ensure the fuse holder is in the open position and remove the fuse. Connect pos and neg to the fuse holder pos top neg bottom or vica versa doesn't really matter. Make sure they are thoroughly tightened. 4. Insert the fuse and close the fuse holder (quick action). If you do have a dc clamp meter you should read just below 12 amps(Isc). Do not use a multimeter on amp scale as the max for multimeters is normally 10 amps. 5. Leave it for around 30 minutes in the shorted out state then climb onto the roof and check all the mc4 connectors for arching or hot to the touch. If all checks out ok it might have been a male and female connector not pushed in all the way( you should hear a distinctive " click" when they seat together. If all is ok after 1 hour with panels in full sun at noon you should be ok. Discconect and assemble the process in reverse. Remember to open the fuse with a quick action the last thing you need is arching across the fuse terminals. DC is unforgiving if there is loose connections that is how your house burn down.
  10. They are priced between R3.5k~R5.9k new https://leroymerlin.co.za/hubble-s-100a-1-2kwh-12v-100ah-lifepo4-first-life-cells?sfdr_ptcid=32806_617_693780197&sfdr_hash=e12e880aa0ba19f812de1438c3d2ab6e&gad_source=1&gclid=Cj0KCQiAire5BhCNARIsAM53K1iMIOjuXtDi4K97zbBXbT-uQ3wlGN9rudB6baZGuVaytTztk-MVLnwaAv17EALw_wcB https://www.geewiz.co.za/lithium-ion-batteries/239015-hubble-s-100a-12kwh-12v-100ah-lithium-ion-lifepo4-battery-first-life-cells-3500-cycles-used-healthy-.html?sfdr_ptcid=2961_617_704975524&sfdr_hash=1199965003260481793799f29fd5914f&gad_source=1&gclid=Cj0KCQiAire5BhCNARIsAM53K1g8g33nU195SyShUGompcD2qZhOO17mMqNHFb01xgfQLlQQ8rZdzt4aAo71EALw_wcB
  11. Sorry to hear that is very unfortunate. Contact your insurance company this morning they should cover the damages. Go through all your electronic/ electric devices to ensure the inverter is not the only device damaged. My sister in law's house in Alberton had a direct hit last year. Big damages 3 tv's, alarm system,stereo,microwave ect ect and her Solis inverter and 2 batteries. It was scary one of the power outlets against the wall was blown completely out of the socket laying on the opposite side of the room with black carbon tracks on the tiled floor. Her insurance company covered the damages. Don't get any quotes until the insurance assessor has been out to your property. Good luck.
  12. I see the op mentioned Lifepo in the title so i assume LFP
  13. Yes for sure 0.2C is a good number. Just to confirm you have 600ah@48v so 6 x 5kwh batterye modules connected in parallel? 30kwh of battery capacity. If that is correct you have adequate solar power to fully charge the battery bank at 0.2C and service your loads.
  14. No the panels will reach voltage just below Voc early morning before current starts to flow. You could check voltage even in overcast conditions it affects the current flow not the panel voltage much. The only time the panel voltage will be 0v is at night when it is dark. Disconnect all 3 panels measure the voltage at each panel they should all measure close proximity then add the 3 voltages together. If panels checks out connect them in series then before connecting to the Victron mppt check the voltage on pos and neg wires and it should be the same as what you tallied up on the earlier sum. If voltage checks out ok connect to the Scc and the blue Led at bulk should stop blinking and turn solid on. Ensure the Scc is turned on under settings page. If you battle to get it to charge pm me then we can discuss your problem via watsapp. Happy hunting. Ps. Check all Mc4 connectors combiner connections and fuses.
