Sorry for the late reply. i Bought the element from JBH solar Lichtenburg. i Don't see a problem if you fit this element in the geyser if you have enough panels or battery capacity. Check out JBH solar website for more options jbhsolar.co.za

Must have something to do with the size and triple coils. It behaved like a electromagnetic induction coil, expansion of the conductor allows for less resistance with heat.

Tested the element on 12v 800Ah battery bank for 2 hours. It consumed 50.10 Ah and heated 150L water from 10'c to 62'c. The panels and inverter kept the soc at 85%.

i Will install it early tomorrow and test it.

So i received a 12v 300w dc element today and it is huge and i mean Huge 50cm long with 3 u shaped element coils. The old one was also 12v 300w and 17cm long connected from the panels (series 4x [email protected])directly to a geyser. i Wonder if this one will work? i Know the amps is on the panels are less and will take longer to heat up. Tested it with 4x12v battery bank and in 10 seconds it was HOT. Does size matter?🤭

I got the element from acdc Germiston for R580. AcDc element is stainless steel. We also have hard water but i use a ion exchange filter system to soften the water. So what you need is a pre heat system. It would be better to use a 2000w element and use the excess pv power.

i Have been searching for a lower watt element for some time now and finally found a 1000w 220v element today in stock for under R700 incl shipping. Its not cheap but still less than geyserwise element. It will be cheaper than extra panels.

i Have installed 8 panels north and 4 panels west and it made a big difference on charging the batteries especially with the Growatt inverter. It seems that the growatt charges in the morning and then again in the late afternoon. The reason for my west facing panels is shading on the 8 panel string from 16:30. My goal is to have the battery at 100% when the sun set especially in winter.

It is 22A. i Don't know if the new 113 version inverters will communicate with the 40.06. The only way is to test it your self and hope for the best. Ginverter does not respond to our questions so it is frustrating to wait and see.... You could try sending a email to [email protected] perhaps they will respond.

Yes it seems so. i Don't think they care much about model numbers just production.

Latest version is 113 01 C.05 114 01 C.05 on the new Growatt spf 5000 es i bought yesterday.

Thanks. I'm use to my other system is the old separate charge controller and inverter.

So i can change the panel strings to 6 panels in series that gives me 228Voc and 9A and the other string the same and that will give me 228Voc at 18A together?

The max panel current is 22A as you said on my Growatt spf 5000es. So does this mean the total of the series strings then parallel to inverter can not exceed 22A?

My Mppt input on the inverter says 450voc at 100A so I'm still well below the max if i re-wire the panels for 2 strings of 6 panels each then parallel to end up with 228V 18A. i Was looking for that nominal voltage point. I'm planning to add more panels soon if the price of solar panels don't go up to much. Thank you for your replies guys.
