Crowz/AlpineJoe, appreciate the info. I've worked with Fred for months and he never offered that solution? I asked the issue to be escalated to his management and now working with Bianca Chen. The first thing she asked was a pic of the label on the controller to confirm the firmware version...

Understand the advantage of pulsed DC and the zero volt crossing to avoid relay arching. However, does it really get down to zero with the filter caps trying to fill the gaps? Also on the same note if you have the DC voltage needed wouldn't a DC speed controller do the same thing but also have...

I'd gladly purchase more expensive American made but nothing turned up in my search? The highest working voltage I found was 60Vdc. I'd like 200Vdc with 10a to run the 4 panels in series. I can run series/parallel so 73.36vdc @ 16.36a but don't want to run voltage any lower. Trying to keep...

Just an update on the EPEVER BN model. I've installed about 8 of the AN models and thought the BN with its higher panel voltage rating and larger heat sinks would be a better choice. WRONG! The BN model overnight will lose its panel voltage and display it incorrectly. If I shut off/on the...

Yea I went back to the drawing board on the element selection. I want to keep the top 220 AC stock on its thermostat set to 120. The bottom I need to change to utilize the full power and set it to 150. NOTE: it's been my observation that the top element should be set to work off the bottom...

Appreciate the feedback. I've been playing with this off and on for the last year. Currently I'm up to 1200 watt (4x72 cell panels) in series/parallel. I was going to run them all in series and push about 150v into the element but was trying to use DC SSR to do the switching. The issue is...
