Budget generator

Recommended Posts

I need a generator

 

I need something that will be used an hour or two most weeks, and 8-10 hours at a time once every three weeks. Let’s just say, it will run about 25 hours/month. It will need to run a computer, two fans, one LED light, I don’t need anything fancy. I would also like suggestions as to what power cord and strip I should run from it, into the house. I would like to keep it out back, so will need about 20 meter cord, that will accommodate use. Inexpensive and something I can order from Lazada will be a big plus.

 

Any suggestions from a happy recent buyer, or anyone with some generator knowledge would be really great. 

 

Thanks in advance.

No neighbors to worry about much. 

 

It will be in a covered lit area, with pleny of ventilation. Auto anything sounds good, but budget is key.

Our neighbour "problem" is that they see we still have all the lights on and wander over to gas with Madam, watch our TV, use our WiFi, eat our snacks and drink my beer (the latter mitigated somewhat by keeping a stock of the local hooch).

 

Your "lit area" won't be when the power is off :whistling: One of those rechargeable emergency lights may be handy 🙂 

 

That little Ramboo for 6 grand with electric start looks pretty handy. That's probably a "Chonda" (Chinese copy Honda) engine so parts would be no issue.

 

Do note that load tends to expand, Madam will probably want her TV (can't miss the soaps) and then "aircon would be nice" and suddenly your baby genset needs a big brother. We have a Kwai Thong 6500 (5kVA) which runs the whole house except the water heaters (only one aircon, our bedroom). It's discussed in the thread linked below.

 

The simplest "transfer switch" would be to arrange everything you want to run to be powered by a single outlet. Then run a cable from the genset to another outlet next to it. Power goes off, go and start the genset then move the plug from the mains outlet to the genset outlet. Quick, easy and SAFE. Please no "suicide cords" (a lead with a plug on both ends, plug into an outlet and power the whole house).

 

Have a read of this thread, if you're reasonably handy you can do much more, the simple "auto-stop" is easy to do and saves your fuel.

Great information. Thank you very much. 

 

Yeah, not sure what I was thinking about 'well lit' area when the power is off. I'll have to send the Mrs. out with a torch to start the thing. 

 

I'm very fortunate my Mrs or kids don't watch TV, and AC drives my Mrs sinuses nuts, so we don't run that either. I took a good look at the Ramboo, it does look pretty good for the price. 

 

Thanks again, much appreciated.

That looks like a nice unit, and the price is right. Thanks for the tip. 

 

Let us know if you buy one and how you get on with it.

The same seller on Lazada has this larger model for 800 Baht more:

Would that be able to run lights, TV, fan and small (250w) house water pump? What about a 13k BTU AC?

Probably marginal for the A/C unless it's an inverter type (no start surge).

 

Our 5kVA unit will just start the 12,000 BTU conventional A/C in the bedroom but doesn't flinch at the 23,000 BTU inverter in the lounge.

Thanks, the A/C is an inverter, so should probably be OK (it's not essential anyway).

 

We have one of these usage monitors mounted in the CU.

I know that they are not that accurate, but the only time we exceed 2 KW is when using the shower heater.

I wish I could get our usage that low 🙂 

 

Standing load is about 900W 24/7/365. Anyway, with an inverter A/C you should be fine 🙂

I used to run pretty much what you want with a 2kVA Honda.  It would bark and rumble a bit when the water pump on and any load over 7 amps would start it jumping.  Do make sure the place you want to put it is well ventilated and protected from direct rain.  They get very hot.  

 

Have you decided how to bring in the power?  Suggest transfer switch between a mains isolator and your CU.

The generator would be placed outside in an area sheltered from rain and sun under our third bedroom and the kitchen balcony.

That is where the mains cable comes up after running underground from the meter. The cable then comes into the ground floor (which belongs to our dogs) and is led upstairs into the roof space via the empty space in a double wall in one of our bathrooms.

From the roof space the cable comes down again to the CU inside the wall:

I would cut the cable where it comes out of the ground and place the generator and the changeover switch under the third bedroom. In order for the cable to reach the switch, I will have to pull 3-4 m. of cable down from the roof space through one 90 degree 1.25" bend, and I don't know how hard that will be (but I think it's doable). Luckily, I left about 6 m. of spare cable looped in the roof space. 

 

In this separate topic Crossy posted about this changeover switch:

I don't like that you have to "split" live and neutral on the load site, the more connections the more things that can go wrong. Don't changeover switches come in a "two in, one out" configuration? Since the load is the same (at least in my case) whether running from mains or generator, I don't see the logic in having to connect the same load to two different lives and neutrals.

 

The switch doesn't have to be as cheap as the one in Crossy's topic, and it would be a bonus if it came in it's own weather resistant box.

Mine does.  I got years ago from Amazon UK (I think) but should be locally available now.  A transfer switch should be, well, a transfer switch so maybe something not obvious for the one above.  (?)
