It's been updated with whatever was the latest firmware, but I'll check again. It just started suddenly, not sure why....I'm putting on my tinfoil hat though, ya never know....................................

Growatt 24v inverter charged fine, then the next day it's beeping and throwing a code 19 and everything was reset as if it was , well....reset. but it was no longer functioning as a 24v inverter, all settings pointed to it being a 48v now. Has anyone ever seen/experienced this? I have a 24v...

This is what the battery display looks like. It repeatedly starts around 27v and plummets to 21v and cycled for a couple minutes like this with only 14w coming in from solar panel

So the sun was barely touching the panel and I was trying to turn off the battery to stop any more discharge from the SCC fans, and then this happens. Even though the battery looks like it is still on, the button is turned off and the charge controller was having a difficult time. It would keep...

I don't know about the best price, but I have used Amazon to purchase 50ft 12 awg pv cables for 62.95. There was another brand that I saw Temco, 80 foot roll for 44.95, but it's just wire, no connectors. I'm sure someone has found cheaper than 56 cents per foot, but I needed it now.

I do have 1 concern: is it possible for a solar panel to produce too much current under normal conditions?

Input can show up to 45v which I was definitely surprised to see, but I only ever see an average of 35v from my panel. Once I wire up the 10 awg cables on thursday/Friday I'll report my wattage. Update: it just rained pretty good and cleaned off the dust, achieved a new world (my world) record...

I believe you might be spot on. I'm going to try jumping to a 10 awg solar cable of 40ftand get rid of the 12 awg 50ft cable I have now and see how much of a difference it makes. If that makes a difference I'll end up cutting the 40ft 10 awg down to 30ft by routing them through a more direct...

Thank you for that explanation, by 'developing a load' do you mean it connects the panels (35v) to the battery(~24v) and feeds it current? Like, it connects it internally and the higher volts pushes current into the discharged battery bringing up the voltage to nominally levels?

Yes, to my knowledge it's new, purchased from IES. I did unfortunately reconnect the panel to my inverter after testing it, while the sun was shining. It took almost a minute for the inverter to start allowing power into the battery. But since it's only 1 panel operating at 35v and roughly 270...

I'll measure with the IR gun around 2pm-3pm today to try and get a peak temp. I can understand the panel & cable loss, but does an inverter typically make your wattage pay tax before it hits the lcd display?

Something else I noticed, the battery will pull 9amps with nothing running on the AC circuit. Does that look correct? Funny thing is with the inverter turned to the OFF position (AC circuit off, inverter still on) the pv voltage coming in will go down below the threshold of 30v and constantly...

I'm on the west coast and have full sun, rarely any cloud cover. Temp today will be about 95F(78F currently). The panel sits almost flat on a patio overhang so I can grab more energy over the course of the day versus being angled directly towards the sun on an angled portion of the roof. But I...

Thank you for the speedy responses, I totally overlooked those things. So I'm actually getting low amps from the panel is what it sounds like, based on the voltage being 35v from the panel. Does that sound about right? Looks like I need to change the post title, that's the most inaccurate thing...

Hello, I'm left scratching my head at the numbers. Am I mathing correctly? 35v x 8a = 227w? Shouldn't it be like 280 watts? I tested the solar panel at the leads and I'm getting good voltage, even with 40ft extension cables, the numbers are still good. I'm using a Cen-Tech basic clamp meter for...
