Hi – I am in Australia and have a 2400W 240AC Heating Element in a 300L tank. I am thinking of using 2 strings of 8 x 190 watt panels to drive the heating element totalling 3040watts and a combined open circuit voltage of 360VDC. We use more panels because in the middle of summer we lose 1/3 power efficiency due to the heat and in winter, even more on cloudy days. For my heating element and your regulator what would be the optimum heating element and solar panel configuration?
Hi.
Looking to use this device for heating my koi pond.
I have 4 x 300w panels
V voc 40.1 V
V mpp 32.8 V
A. 9.05
Using your calculator I’ve worked out I need 240V. 2700w element? Have I got this correct?
However in UK can only get 2500w or 3000w element,which one should I use?
When I do my calculations should I use voc or mpp volts?
What is the min and max settings on the temperature probe?
Hope to can help me

Hi,
perfect device, still waiting for my PV modules to do instatllation, so I can just read, I have 2 questions;
1) Have got parameters and diagrams from my moduls and heater resistance, how to adapt best(mode 2, example ?)
2) Has your controller any interface or simple output, wlan,RSxxx,xxxx to collect operation data in my home automation system?
Does your website have a contact page? I’m having trouble locating it but, I’d
like to shoot you an e-mail. I’ve got some suggestions for your
blog you might be interested in hearing. Either way, great blog and I look forward
to seeing it improve over time.
