  1. Hi Morney Yes you can install a lithium battery for the inverter, should not be difficult to open it and replace the battery with a lithium. IF you don't want to spend too much money you can order a 50ah battery from Geewiz for like R3510 with free delivery https://www.geewiz.co.za/lithium-ion-batteries/202973-lalela-lithium-lifepo4-battery-12v-50ah-640wh-2-year-warranty.html
  2. yes the reduction in battery AH capacity was as a result of the battery firmware upgrade.
  3. I seen the same, had 3 older ones and 1 new one, after firmware upgrades my inverter only see 400aH
  4. Thanks all, but none of the solutions will work for my needs, need something that alert me when the battery drops below a certain voltage, the cutout switches are great for dual battery type situations but not for my setup.
  5. hi , the inverter is a 1440w small one, does not have any settings to change
  6. My mecer inverter was built for lead acid batteries so does not shutdown before my lithium battery goes completely flat. The battery goes into protection mode and I need to wake it up with another 24v battery. Does anyone know of a 24v battery voltage alarm or buzzer to warn me when its low?
  7. hi Modina, thank your for the detailed response. Although my system is AC, the inverter has a fairly good efficiency of 90%, compared to some of these backup trolleys with inverters that has as low as 60% efficiency, the downside to a DC only system is you cut out your AC devices for utilising it, as well has the complexity of having to cater for different DC voltages. MY main selling point is having batteries with 3000+ cycles compared to the Ecoflow/Gizzu's etc you looking at 500 to 1000 Cycles. Mine is modular so you can easily upgrade or replace components. When these other small fancy boxes fail after warranty period you sitting with a big door stop.
  8. I needed to find a solution for my parents and mother in law to watch tv and run Wi-Fi etc. during 4 hours continuous load shedding. Built 2 system 9 months ago in a plastic utility "ammo" box and works very well, their friends and my people at work asking me to build for them to , so "JuiceBox" started. 350W pure sine wave inverter, 640wh Lithium battery and 7ah Victron lithium capable charger. Here's my FB page, I sell them for R8750 each and can ship anywhere in SA. https://www.facebook.com/JuiceBoxSA 2 page Brochure.pdf
  9. This is the charging characteristics of the solar charger I am considering using, should be OK to use it with standard values.
  10. thanks that is my plan will keep you guys posted
  11. thanks, I am also testing using a regular 10A solar controller with a 8.3amp 12v power supply (LED driver)
  12. thx have looked at this but need 100% SOC charge ideally
  13. Not wanting to shell out money for expensive Victron or Optimate 12v life charger, is there any alternative that is more affordable? Looking for something that can charge a 12v Lifepo Battery at 8 to 15 amps...any ideas? Maybe ideas to build one myself?
  14. thanks for this, where can one see the release notes?
  15. hi Jay I have the same installation as you, but never seen this, think it's good idea to have firmware updated as a starting point.....
  16. Hi Nate. 4kw geyser element still in place. Cudub Holdings did the install. Very happy with their work and good pricing On the 12kw 3ph model one phase can go up to 6kw
  17. Our 12kw Sunsynk is in a cupboard and does not get past 33 degrees. Made ventilation holes in top of cupboard for air to escape into celing and vents at bottom of cupboard doors to suck in cooler air. Cupboard is inside house so much cooler than say our garage. I guess our inverter runs cooler as it does not work close to it's max capacity. Also in the cupboard are 3 hubble batteries I attached 2 fotos
