Our off grid system uses a Growatt 3k AIO. It consumes a fair amount of power in standby mode. This is not an issue most of the year, but does become problematic during NovDecJan. the Growatt has been powered on continuously for over a year and works well. When we are away it is powering...

I am planning to add three 350w (3s) 1050w at 108v to our Cabin system. We have 9.6 kw lithium batteries, 3k Growatt with 490w (4s) 1960w arraoy at 208v. 9 months a year it works great. Winter months have short days and low sun here. We are looking to add 3 Panasonic 350w panels that we picked...

Hello to the forum. I Have been reading here for over a year as I researched for the construction of our system. It is now time to ask some questions or answer those that I qualified to speak on. Thanks to all contributors who have come before as this info is very helpful for people starting...

I am fairly new to solar and have no experience with grid tied systems. We have an off grid cabin that we have successfully implemented a full off grid setup so I understand the basics. I am now looking to set up a backup system at our full time residence so that if the power goes out we don't...

We have a off grid system that occassionally runs out of sun in winter. After a week or more of low production they system has shut down for a short time. We use a cheap 450va APC ups to keep internet connected for a while after the system goes offline. This works well and does give me the...

I have 2 25w panels in series. The made 13.19v separately, in parallel, and in series. What am I missing? I am using a Victron 100/15

I would like to permanently install a Victron 75/10 mppt to our vehicles starting battery. This will give me a nice bluetooth battery monitor as well as the ability to keep the battery topped off with a small panel. It can also be used as a switch through the load connection. My only concern...

I have been contemplating how to future proof our small off grid system. We have a Growatt that has working perfectly fine for 20 months. Unfortunately it looks like the China AIO units aren't going to be well supported. Watts247 has disclaimers on some MPP and Growatt units that they will no...
