  1. I try not to discharge lead batteries below 70 SOC. Use ballencers and checked them regularly. They then last a few years depending of the quality of the battery. I have found that the maintenance free batteries of cars run low on electrolyte after 3 years. Their life can be extended by opening them and correcting the electrolyte levels. Thanks for lithium batteries they make life less complicated.
  2. The reason for my setup is also to get maximum battery life out of the batteries. If 1 off the 12 volt batteries fail, I use the rest in lower voltage inverter until they are of no use.
  3. @SassI also use my old Lead Crystal batteries as a extra source off power. Main inverter on Pylontech batteries. The second inverter is not connected to Solar panels. When we need extra power we switch on the 2nd inverter witch has its own plugs. If the Pylontech of the main system are fully charged we charge the Lead Crystal batteries for the next time we need them. Running like this for 2 years. Use ICC to know when the Pylontechs are full and then switch on the charging for the Lead Crystals with Sonof Wi Fi.
  4. I have a few hundred of these lights. They are in a sealed watertight plastic tube. The lights are 1 meter long. 0.333 amp 4 Watts. Still thinking of what the possibility is with these or maybe sell some
  5. I really thought you were wrong but a clamp meter agree with you. Thanks you for the information
  6. Easy to install with excellent service from Pierre. Software at a good price.
  7. We run most off the water through 50mm pipe to the main heating panels on the roof and the rest of the water through this 20mm pipe connected to the flat panel heat collector . This way we benefit from both heaters and have a balance in the water flow.
  8. You don't need to run all the water through the heating system. I installed a T piece in the outlet pipe of the pool filter and use a watertap to control the amount of water going through to this heating system. There is some heating panels on the roof. This pipe feeds water to a old flat plate collector for extra heating. The normal black pipe wall thickness is very thin and only last a year or two. Try to get good black pipe with a thicker wall.
  9. Want a 250Watt poly sp enersol solar panel or semilar to replace 4 year old panel with hot spot. Would also think of 2nd hand. Thanks
  10. If you reset the Geyserwise. Swith of the power supply to the geyser. Then also disconnect the battery or solar panel so that there is no power supply 12v and 220 v and then restart.
  11. I installed solar assist and experienced some installation issues, but with the help of Pierre at Solar Assist who assisted us with the installation it was running in no time. It was great service and I would definitely recommend Solar Assist.
  12. @AntonDjCheck your setting 29 Low DC cut off on both inverters. This could be the diverence

  14. With the dry contact set to 51v on and 50v off the geyser will only run in this range. If any other large load example the oven is on then the oven will receive priority, the geyser will switch off. If there is not enough solar power the battery voltage will dip below 50v and the geyser switches off automatically and will not drain the batteries. We're running off grid, this voltage range works well with our batteries and system.
  15. Although the geyser is connected through Geyserwise and I have the simpel old Axpert inverter, the supply to the geyser is also controlled by the Dry Contact of the inverter. It will switch off when the battery go below 50v. This with 2kW element works good and inverter and batteries are well protected.
  16. No I will just add panels to my existing solar setup. During Winter I have enough power to heat the geyser. Summer time we run a pool and will need an extra 750 Watt for a few hours a day. The geyser was done a few years before the solar. The EV system has too much maintenance. The water pump failed this week. It also melted the insulation tube covering the copperpipe on the roof. The pipe was at 144° C when the pump failure was discovered.
  17. 12volt pumps we use does not last long. Replace 1 and repaired 1 in 4 years. Also replaced flat plate collecter with burst pipe with EV tubes. To much maintenance, if I have to do it over it will be PV panels
  18. @ViperGTI. Something to think about in your planning. Installing a stove top with LPG and electric plates combined.It will cost more but it is worth the layout. We started with LPG only before installing solar. Later we leaned that we have extra electricity that we don't use. I then installed a Elba stove with 2 plates. These stoves use power depending what your setting is, no1. Uses only 100Watt going up to 1000Watt at setting 6. The big plate is 100 to 2000 Watt. These plates draw a constant current, so no on and off switching. We now cook more with electricity than LPG now.
  19. Cycle 3 x 3000 Pylontech 35% daily and rainydays 50% . SOH 98% after 19 months 224 cycles
  20. Removed the sealing tape of a 30 month old LDV battery. The top of the lead plates was not covered by electrolyte. Top this battery up a few times and still going.
  21. We pay R289 connection fee per month to be offgrid. Maintenance came to a complete standstill. Last month I had 2 council guys to check my installation and ask what is the rules to comply. The inverter was checked that there is no AC in connection. They said there is no rules yet. Our meter was sealed because we don't buy electricity. I was told if we don't buy electricity they will replace the meter. They must try a new version.
  22. Sorry you are right they are connected in series. You must connect them in parallel your voltage is to high.
  23. How is the panels connected. Series or parallel. They muut be connected in series to keep the voltage in the 30v to 66v range of the mppt.
  24. Do anybody have any experience of the inverter software for Axpert inverters sold by Micro Fusion computers. Thanks
