Apologies yes, they are in Series with the cold water supply feeding the Secondary and the Secondary feeds the primary which ultimately feeds the home. I do have the plumbing to switch to user only the Primary or only the secondary but never do that. Both operate independently with 2 hotbots controlling the temps. The primary is heated first from schedules and/or excess solar and then if there is additional excess the secondary is heated. So essentially its 300l made up of 2x150l which allow me to not HAVE to heat the full 300, whatever I can get into the secondary is bonus and helps the primary out. Works really really well for my requirements.
Old post, but for what its worth I am using 2 of these units on a Parallel Geyser installation, secondary feeding primary, feeding the home. Works 100%, set and forget really.
Hey fellow green energy humanoids I was just wondering how people are configuring their SunSynk/Deye SOC schedules these days now that Load Shedding is not such a huge issue. I understand the general idea is to be lower in the mornings and build in the evenings, so something along these lines, but was interested in what others are doing. 06:00 - 30% 10:00 - 20% 15:00 - 60% 18:00 - 100% 20:00 - 80% 23:00 - 50%
