Hello there,
I am using at home normal electricity with standard meter,
and off grid solar power (switch to normal electricity or solar).
I am planing to ask for a netmeter to my electricity supplier.
I already have an 1300w grid-tie inverter, so my question is: is it possible to test my grid tie inverter with the offgrid solar power or normal electricity without netmeter? if yes there is no risk to burn something?
I just want to test it to see if really it produce 1300w cause my panels are 1600w.
waiting for your help.
 
Please post a link to the product specification for your inverter?
Also what is the mains electricity standard for your location?
 
Do not test it with the solar inverter (off-grid). You might risk burning your offgrid inverter by backfeeding into it.
IF you want to test the GTI, do it at your own risk, but only with grid power.
Please note that you need to consult your local regulations because backfeeding into the grid (without net metering and/or contract with your electricity supplier) might be illegal.
 
Thanks Smooth Joe,
The mains electricity is 230v 50hz the grid tie inverter 230v 50hz dc input 22-50vdc 1300w.
1 green led
1 red led
thats it.
Thanks meetyg, so it is a risk to burn something.

That is not actionable intelligence.

Wow that looks nasty.
Potentially live pins are dangerous.
I hope it looks for compatible ac before it energizes the ac side.
I would not be surprised by anything though.
Be very careful with that.

I have a similar one from MarsRock, but 1000w. Mine has anti-islanding. This could be easily checked using an AC volt meter: When DC power is applied, check the AC cable (not connected to the grid, only to the inverter), to see if there is AC voltage.
If it has anti-islanding, there should NO voltage on the AC side.

But again, do NOT use this connected to an off-grid inverter.

Mine is not in use anymore. But just recently I needed a large load to test my 24v DIY LiFePO4 pack, so I put it into use (why not feed the power back to the grid instead of just wasting it...). Thats when I noticed that it didn't play well with my grid-tied microinverter.

Ok, I'll do that to see.
Then I'll try it to a frend who use ongrid solar power
 
Hello,
did anybody compared the GTI 1000 / 1200 / 1300 models?
Maybe they are the same inside. It's just speculative but

1st I saw this with the cheap GMI micro inverters, I tested the 260 / 300 / 350W models and they are all the same inside and deliver 300 watts.
2nd on ALiexpress I only can find a repair pcb board for the GTI 1000W and nothing for the 1200W and 1300W

Did someone already tested out how much power the three models can deliver?

edit:
maybe I should open a separate topic for this question...
 
I had a 600watter and it delivered 595w when connected to my 24v battery bank, it didn't last long though, I think those cheapies are a waste of money waiting to happen...
 
I have a couple of GMI 260W micro inverters at A$66 each. They have been running for about a year and they each produce about 2KWH a day in addition to my 10 year old 1500W grid tie system.

The GMI micro inverters just plug into a standard 240V socket which concerns me a little, but has worked OK. They were to boost the existing systems drooping ageing panels. I've been running them off second hand 250W panels A$50 each

They have been working fine but need to be sealed with silicone to make them waterproof.
