6.5KW Split-Phase Pure Sine Wave Hybrid Solar Inverter

These were easy to install and work great I've had no problems other than shipping and they replaced the board and 2 panels which got damaged in shipping the units seem well built

I put 2 6500 units in my garage to create 220 voltage for my home. The units were easy to install. They are a bit noisy but I've had several other brands and these are comparable.

Went with callsun because a friend had one and liked it. Took a little bit to get and had a couple hiccups but emailing there customer service was great and got it solved in know time. Have been using for about 6 months and the biggest problem I've had is lack of sun. Lol. The inverter has cut down on electric use from the utility and is nice for back up if needed. I watch the app all the time seeing how many watts I'm making.

Purpose of this system is to act as a backup generator when power is out. It was set up with (14) 450 watt panels and (4) Batteries as seen in the photos.I currently run selected branches continuously on solar and battery. I also have an electrical source available when batteries reach a specified voltage.I agree with other reviews in regards to decibel levels when systems are running, It wasn't a concern for myself because I installed the system in my garage, and have not noticed it to be an issue in my home.I actually enjoy the sounds, as the inverters increase in decibels when energy is increased via solar to the system. You know power is being generated.All in all, this off grid package has delivered for my needs.

Installed two 3 phase systems at my production warehouses, seems to be working great. Installed 6 months ago.Systems are set to S-B-U mode

Purchased a single unit at first and the added a second one; units are setup in parallel. Systems are set to S-B-U mode. Using the units for running a few critical loads; Inverters have been installed and working for about one year now and have been working well. I have also purchased 3 server type lithium batteries and 8 450 watts solar panels from this company; all working well. Every time I have contacted them they have responded promptly. I would order from them again; in fact I will be adding more solar panels soon.

Powerful inverter, not heavy, delivered fast. I will get more solar panels hooked up. By now it can power my cabin with battery easily. Easy to set up, too. Recommend it.

The Callsun 6.5KW inverter has been an absolute game-changer for my off-grid system! With 5kW of solar panels, 800Ah of LiFePO4 batteries, and a 9kW dual-fuel generator for backup, this inverter has seamlessly tied everything together, ensuring my home runs efficiently and reliably.What I love most about the 6.5KW inverter is its robust performance and versatility. It handles my major loads—like a full-size refrigerator, Mr. Cool 12K heat pump, Starlink internet, and multiple TVs—without breaking a sweat. Even with two fully equipped home offices (computers and three monitors each), the inverter keeps everything running smoothly, even during peak usage.The pure sine wave output ensures my sensitive electronics are safe, and the inverter's ability to integrate with my generator is a lifesaver during extended cloudy periods. The transition between solar, battery, and generator power is seamless, and I've never experienced any downtime or flickering.Additionally, the user-friendly interface and monitoring capabilities make it easy to track performance and optimize energy usage. It's clear that this inverter was designed with off-grid users in mind, offering reliability, efficiency, and peace of mind.If you're looking for a dependable inverter to power a modern off-grid lifestyle, the Callsun 6.5KW is a fantastic choice. It has exceeded my expectations and made off-grid living not just feasible but incredibly comfortable! Highly recommended!

This inverter is absolutely amazing. Easy to install and operate. I shipped it all the way to Haiti 🇭🇹

Installation was pretty straight forward. Connected to solar panels 2 batteries and connection for generator. I run some items in house continuous from battery back-up. Utility company goes down every so often and I can easily switch to battery back-up. Inverter works well.

6500W DC 48V inverter - Install was easy. More important is I have an off brand battery and customer service really helped me and walked me through how to sync the two. I have found the performance to be as advertised, and have had to call customer service a couple of times when I want to tweak little things like level of battery charge etc. I added a couple fuse breakers for extra safety. I dont have any really large loads so I have not been able to max it out. I am running 240 split phase and it handles it like a champ. It has even more features I can use, but have not had a use for yet.
