I'm one of first kick starters who pledged to OUKITEL P5000 Pro.
Before the Pro model was available, OUKITEL is kind enough to send me a P5000 to use. As a green power advocate, I've created a solar corner in my house where everything is powered by solar. I've connected a freezer, a water heater (800W), a rice cooker and an oven(1000W) on the AC outlets. I charge the P5000 through a fixed 600W solar panel and occasionally through AC. The unit performed miraculously during my 3 months usage.
Then I received my Pro model which added the WIFI connection option and Apps to monitor the status of the unit. I'm in US and it turns out the App Wonderfree works better for me.
The Pro worked flawlessly 24/7 for another 4 months then lost AC output and display one day. I reached out to the support team. After a few email exchanges, they added my Wechat account to speed up the communication. To help me send the unit back for inspection, they kindly sent me an empty box with all the packing materials and free UPS pick up. Once they received my unit, a brand new P5000 Pro was sent to me within a few days. Kudos to the excellent customer support of OUKITEL.
Here is a picture of P5000 Pro work side-by-side with Ecoflow Delta Pro. The flat top of P5000 Pro is great for stacking an oven on top to save space. P5000 Pro works as the main unit and Ecoflow is my backup to store extra solar power. The UPS feature on Pro works great which allows me to use Ecoflow's AC power to support all the AC loads on Pro and charging Pro at the same time.
Another picture shows I've connected 3 200W portable solar panels in series to collect extra power. The 1st solar panel is from OUKITEL, also very good quality comparable to the last one from Bluetti.
I only give 4 star due to the unfortunate break down of 1st unit. I hope my 2nd unit will withstand the test of time.
I give the customer support team 5 stars.
