I saw 65amps going into my battery with the same unit yesterday . Set it for 80, and you’re good. I have 5000W of solar on the one inverter.

Although vaxxed and boosted, I watched him for his worldwide monitoring, and UK rates as the US follows the UK rates by a month. I’ll give someone the benefit of the doubt, but too many, you’re out. I stopped watching him after this abstract ”review” because he’s chasing clicks and not...

Devices are usually designed to self discharge for the benefit of safety, so yes, more than a couple of minutes, the safe bet is to precharge with your resistor of choice.

Bad move by Campbell… he promotes vaccination , but is armchairing everything. in this case, an abstract is not peer reviewed science. I’m still waiting to see the data behind the abstract posted on an NIH website. Are you willing to bet your life on this guy...

just use an old incandescent lightbulb… it is just a resistor after all…

First, let me say, the product setup documentation is aweful for this product. This can’t hold a candle to Enphase monitoring with even 5 year old gateways. Overall, it seems that monitoring is an afterthought for Growatt, strangely for a good inverter with an affordable price point. After...

With AIO (Growatt, MPP), you don’t want to back feed into the main breaker, rather move your critical load to a new sub panel downstream of the AIO. All solar generated via the AIO will be used internally. Bad things will happen if you attempt to close the loop. Follow the electrical code...

Install a AiO, add a critical load panel downstream, and you’ll take back control of the Kw your system is producing. Size your battery to your 24hr consumption.

For tinkerers, this is the standard approach which I identify with as well. The industry at large has become a lot more cost effective. My suggestion for newcomers is prior to pulling the trigger, write up your wish list for your design and do an energy audit. In the end, you’ll spend less and...

Do you have Option 4 for energy saving? I think that might be your problem.

I agree with all your points as well. What I don’t understand is the need for additional complexities of installing transfer switches and the like.

People should commit to installing their AIOs to their locality’s respective electrical codes for safety. To be blunt, don’t half-@ss it, electricity is dangerous, My suggestion is that people install their AIOs as if it’s an enhancement to their main breaker by sizing their AIO purchase to...

I’m not sure why everyone is wiling to spend a lot of up front costs for an AIO, and then treating it as a generator. It’s better to consider it a UPS. On my 3 bedroom home, a 3000 watt generator has satisfied my needs during multi week power outages in New Hampshire. No fun filling jerry...

looks like you changed a lot of settings from default. I’d look at setting 14, and change setting 4.

Here’s a DC wire size calculator. Remember this is all about making sure the wire can carry the power from the panels to the Mppt charger efficiently. Note that watts are not part of the calculation, it’s all about the flow, distance and resistance. A good analog to this is water flow through...
