This is a solar powered generator review, and yet the one thing you don’t mention at all, is how long it takes to charge with the solar panel ??!!!? Do you have that info I feel that’s the most important aspect
I want to see a solar power demonstration with a 1500 heater that can run continual power with a Jet air heater ! Also if they can be connected to double the power
What about Rennergi and Terri compared to Bluetooth and Ecoflow ?? How do they rate next or above them fir continual power ! To run a heater in below zero weather for winter camping in a van !
There's no such thing as a "best" solar generator. All of the so called solar generators on the market have one glaring flaw that no one ever talks about. That flaw is the fact that all solar generators use low cost (cheap high frequency inverter technology to convert the battery's DC current into AC current. None of the Chinese made high frequency, transformerless solar generators on today's market including the Oupes last very long. They are of a high frequency, transformerless design and the cheap Chinese manufactured MOSFETs and capacitors used in these units cannot take repeated exposures to high surge loads such as full sized refrigerators, large power tools or large microwave ovens. Without an iron core, copper wound transformer to absorb the back EMF and high surge demands of these high inductance loads, typically after about a year's worth of use these expensive solar generator will become a non-repairable brick. You might be able to start and run some high surge loads when this inverter is new but every time you fire up or shut down that inductive load, you're shortening the life of the MOSFETs in your solar generator. They also run much hotter than low frequency, transformer based inverters which makes the low cost, off spec, Chinese made components such as capacitors, diodes, resistors and ICs that are used in these cheap solar generators, far more prone to early failure. This is especially true regarding the amount of electro-mechanical wear on solar generator’s low cost capacitors. Inverters rely heavily on capacitors to provide a smooth power output at varying levels of current; however the electrolytic capacitors that are used in these solar generators have a limited lifespan and age much faster than dry components. Capacitors are also extremely sensitive to the high temperatures found in these solar generators. Capacitor electrolytes evaporate faster at higher temperatures which can reduce the life of these components. Another major consideration with these high frequency, transformer free solar generators is safety. All it takes is for one of their MOSFETs in the inverter's H-Bridge circuit to short to ground or the control circuitry to fail, and these units will send dangerous, high voltage, high amperage DC current straight to your connected AC loads which will not only damage most AC appliances but can also set those AC appliances on fire. Another consideration is that the vast majority of these solar generators are non-repairable. After the warranty runs out, most consumers will not be able to afford to ship these units back to the manufacturer in China to have them repaired. And at a typical shop rate of $125 per hour in the US, with no schematic and limited parts availability, it won't make economic sense to even attempt to repair one of these units. Once the FETs have fried and have taken the inverter's PCB with it, (And trust me, sooner rather than later, they will fry.) they basically become a brick. A far better alternative is to invest a little more money and purchase a hybrid, low frequency, transformer based inverter charger and a LFP battery. Your system will last far, far longer, it will run much cooler and can easily power high surge loads without being damaged. I know this to be true because I've spent the last 23 years repairing inverters. High frequency solar generators simply don't last when powering inductive loads and can burn your appliances, van, EV and even your home to the ground.
The simplest way to DIY a low frequency, transformer based solar generator is to purchase a hybrid, low frequency inverter charger. This is an inverter that has a built in MPPT charge controller that can automatically charge your batteries from an AC outlet or a generator. Many of these low frequency inverters also include an automatic generator start connection for when your batteries get low. Next simply add batteries of your choice Lithium Iron Phosphate would be my recommendation. Add a DC disconnect on the positive terminal between your battery and the inverter. Mount the inverter to a piece of plywood on a wall and wire up the inverter to a subpanel that you have your home's critical loads connected to. Some good choices for the inverter would be Schneider Electric, Outback Power, Victron, Sigineer Power (low priced) or magnum energy. The Sigineer unit has a built in MPPT charge controller, the others do not. This design will last you many years longer than any commercially prepared solar generator, it will provide a much higher surge capacity, it will run much cooler, and cannot damage your appliance during a catastrophic failure of the MOSFETs@@Sasparilla400
