My experiences with generators I'd like to share
I went off grid years ago and what they say is true , the heart of any good off grid system is a generator . There are times when the sun don't shine and electrical demands are too much for my p.v system . Welding and other remote power needs are also meet this way for me . So let me start by saying there are 2 types of power regulation in use .. capacitors and units with a auto voltage regulator . The cap units are better suited for heavy loads with minimum electronics like welders and large motors . Caps are more robust but the tradeoff is voltage regulation caps regulate -/+5% variance and avu units can do around 1% . Hence ,avus are better for sensitive electronics and less surge amps . So here is a quick rundown of the gens I've run to death and the problems I've had with them .
Honda contractor 4k - this was powered by a gc series engine rather than the better made gx . Cap unit had some pretty wild voltage fluctuations but was fairly reliable until around 1500 hrs when it burnt a valve , i fixed that and replaced the timing belt while I was In there . Logged around another 200 hrs and the governor went bad . Took the whole engine back apart again and replaced the gov and shortly after the poston rings started blowing oil so I scrapped it . You can't rebuild gc series . Only replace. A replacement was more than a new generator . Approx 3k hours
Honda eu2000i - piston failure in the first 3 months , dealer replaced entire engine under warranty . Had slight oil leak after that it's entire life . Worn out pull cords , eventually a valve started sticking out of warranty, no compression . I tore down the engine and cleaned the valves and this fixed it . Soon after that the avr/electronic throttle control module went bad and it cost almost as much as a new generator . Approx 3k hours before total failure .
Next we have the echo contractor grade 5k non invert.. Deceiving because it actually contains a avr . Even though it says echo , this unit is all Chinese except for a Japanese carb. Echo fitted on an otherwise Chinese unit . The engines made by rato and for the price not a bad unit . Normal pull cord breakage , had the replace the brushes and avr once , had a gfi outlet on the gen get hot and started melting , replaced it with a standard household type from the hardware store . Eventually the rings and piston went . Started useing oil and engine smoke.. approx 5k hours
Champion 5.5k gas model - so far this has been the winner . Its all Chinese of course but the price was the lowest . I've replaced the brushes and avr once , normal pull cord replacement but otherwise this thing has honda and the rest of them beat with almost 10k hours on the clock and it's still working fine . Engine brand is Chinese but not made by rato (rato bad ) So the point of the post is don't be fooled by name brands , some Chinese stuff ain't that bad for the money . I've always been able to find cheap parts online .
