I've purchased 26 panels, 4 inventers, and 6 batteries, etc. and I can never get any help from them. The one time I got help was a year ago on the phone. Be prepared to wait. Their email support is useless. They will key in on one thing and bail on the whole email. Buying from them is easy...

I have two 3K growatt's connected in parallel now. They are running 120v. All is working good now. What I'm thinking of doing is adding another system so I can run the 240v circuits. My plan is to have the two 3K's run the 240v and get a new 5K to run the 120v. But I'm not sure if you can...

MY Growatt's call for a 100 amp 60 vdc circuit breaker. But I can only find 100 amp 12-48 vdc. Are these ok?

I can't find a thread on protecting the equipment from freezing. Everything I find is about batteries while charging. I'm planning my next project with the equipment in our shed. Growatt says to keep it above freezing. What direction should I be looking for a solution? Thanks

Will's video using the Growatt and a 48v battery rack, so simple. I got started buying the parts but I'm stuck on Growatt. I know to get the US version but it's not UL listed and it has me worried about code violations... I've been looking around and it's hard to find a substitute. I've found...

I have a 24v setup (27-28 usually) that can jump to 50v. The highest values I've ever seen are 21 amps and under 600 watts. I've measured the V output from the combiner box to verify what the charge controller is showing. Is something not working in the combiner box? Any help is appreciated...

Has anyone tried something like this to limit startup current? https://www.canford.co.uk/CANFORD-AC-MAINS-POWER-INRUSH-CURRENT-LIMITER

I'm reading the manual for a Victron MPPT 150 - 45 SmartSolar Charge Controller. I just would like clarity on grounding. In the manual is says don't connect the charger to a grounded PV array. I must not understand that statement. I have a combiner box with a ground and lightning protection...
