Buying a cheap hybrid solar inverter VS a upper medium range

[eddysacc]

I would like to upgrade my sytstem which is grid tied now. Running an 6kw Invt grid tied inverter.

 

Now we need at least 10kw in panels.

in the future when the 3 kids (or more 😅) get their own rooms with aircons it would be nice to have the option to add more panels.

 

My idea was to buy a 16kw single phase deye hybrid inverter.

But the 100k Thb are not really in the budget right now to be honest. Having children is always more expensive then thought i guess. 

 

So recently i saw the PowMr hybrid inverters. They look good for the wallet.

 

There is a 10.2 KW hybrid for around 15k Thb in promotion.

Any experience anyone.

 

Would it make sense to buy a low end quality PowMr hybrid inverter? Or would that not be wise?

Any other options?

 

 

 

I would need to buy 10kw+ of life4po batteries. But thats anotehr topic.

Look into some 5K deye. Crossy got some at a good deal..look into his tread

Can buy a deye 5kw for +- 30k thb.

 

I need 10kw or more.

 

This would be 2x deye= 60k thb

Just in general it is not a good idea to buy anything power electric of low quality cheap.

In good quality equipment there are security features included, and it is designed to be still save when it fails.

That is where lots of cheap electronics don't spend money. It still works without security features.

IMHO don't buy anything which could cause fire or electric shocks because you don't want to die.

Yeah, I've got the original PowMr 5k5 one, and it's been providing 80% of my homes electricity for the past 2 years. It even managed to shut itself off when my 14yo niece shorted the live and neutral together while using an extension lead. No bang, no shock, as fast as an RCBO.

 

Had to turn all the breakers off and on to restart it, but that was the only shutdown in those two years.

 

Paid 13kbht for it and that included the WiFi dongle. Fan is a bit noisy sometimes  is the only complaint I could pick with it. A solid bit of equipment that does the job.

PowMr is towards the low end of the Chinese manufactured gear. It tends to work OK but lacks the features and, important to some, support and repair network.

 

Do be aware that the unit you link to is stated as an off-grid hybrid so check the spec. carefully, it may or may not do grid-assist (draw grid power to top-up the solar is necessary).

 

GroWatt and Deye are more towards the middle of the range, we have three 5kW Deye hybrids running in parallel.

 

The Deye units have the useful feature whereby you can hook grid-tie inverters to the "Gen" port and they will generate even when off grid, of course this means you can continue to use your existing inverters if you desire. We got our units from Lazada, with vouchers just under 35k each.

Also, if & when PEA/MEA start paying a decent rate for buyback excess solar, the 5kW Deye inverter is on their approved inverter list.

 

Two 5kw inverters give you redundancy also, if one does have an oops.  If sticking with PowMr, then two 5kW might be the way to go.

 

We also use Deye, an 8kW inverter, 2 yrs running, flawlessly, and only regret is not going with two 5kW inverters, for the extra juice & redundancy.

 

Big price difference though, so if budget is a concern.  PowMr seems decent along with @BritManToo having good experience using 👍
