Like many things, if you keep finding better solutions you will never actually buy anything ???? Its a good point, but in a way i use to have good experience taking it slow at times too. Now i have looked into Sorotec who is the company who both sell and make inverters like the Easun, but with possibility for parts and service who is ++ GROWATT SPF-3500 and 5000-ES PV and Grid supply power to loads together if PV power is insufficient. its a hybrid right?

What i try to ask if it was a hybrid and if it can blend pw power with grid power for home load? I saw on Lazada. I had the impression that hybrid inverters just switched between power sources, but great if the can blend. Pink Link to comment Share on other sites More sharing options...

My understanding is that the Growatt CAN "blend" as you say, up to the maximum rating of the inverter. The whole area of "hybrid" inverters is incredibly muddy and careful reading of specs and manuals is required. Some units which are described as "hybrid" do indeed simply switch to bypass, rather than running in a grid-supplemented mode. 1 Link to comment Share on other sites More sharing options...

Pink I normally set my inverters to SBU priority to power the house/EV (load) first with Solar, then Battery and finally Utility (the grid) I have set my batteries to only charge from Solar. You don't want to wake up in the morning and find that your batteries are at 100% state of charge because they have been charging from the grid all night and then all the next day's solar production is wasted. So at night I power the household load from batteries and in the morning gradually solar will ramp up until it can fully cover the load then it will start to charge the batteries. As a result charging is slow and gradual and not a big drain on the inverters. Depending on your household electrical load normally load will be closest to the limit of the inverter. In my case my house is well insulated and my aircons are only 8,500 BTU, I have solar thermal and no electric cooking. However I do have an EV which draws a lot of power. 1 1 Link to comment Share on other sites More sharing options...
Pink7 Posted August 16, 2022 Author Share Posted August 16, 2022 (edited) The Revo 2 is B9000 more than the Powland i posted before... 17k vs 26k (25k plus 1200 for parallel). Wife translated Muhendis review on Revo2. Seemed to be quite strong both in physical construction and to serve power. If price difference is most for color touch screen im fine without that. I would prefer connection to my pc. Importing is not what it used to be..$200 in delivery for 3x Growatt 5000.

Popular Post Crossy Posted August 16, 2022 Popular Post Share Posted August 16, 2022 IF you plan on going for an off-brand inverter (which will likely be just fine) and IF you may want to expand in future then I would get two inverters now, then they are guaranteed to work together. For Growatt I would be less worried but even they will change the design sometimes likely with no guarantee of backwards compatibility. EDIT Yes, I know I sound like a broken record, but Thai Contractors and Asean Now members can be like computers.

I agree with @Crossy. Maybe somebody on the forum has used Powland and can talk to the support available. Growatt have Thai support which I have accessed. The guy is called Banana (กล้วย) and is able to speak reasonable English - I can pass on his Line and email to anybody who needs it. 1 Link to comment Share on other sites More sharing options...

Im happy for all input Crossy. Whats the weak or limited part generally for all in one inverters? What operation / part of unit is good to have extra not used capacity?

What operation / part of unit is good to have extra not used capacity? Difficult. I would say the actual DC=>AC "inverter" itself, is going to be the most highly stressed area, certainly any mains charger should see little use, with the MPPT controller being sort of in the middle. The only way to be reasonably sure would be to follow the online user groups and see what failures other users are seeing. but with an off-brand unit that may not actually be much of a user base.

Pink7 Posted August 16, 2022 Author Share Posted August 16, 2022 SPF 5000 ES looks like a good solution but its max pv voltage of 450v and i have 2 x 455v so then if SPF 5000 ES i need 3 units not 2 as the others who is 500v limit. Im not set on the Sorotec made units yet.. even Mppsolar is not out yet. Do some ad mppt controllers to improve charge capacity of a all in one setup?

Pink7 Posted August 20, 2022 Author Share Posted August 20, 2022 I have plan to use a Dual Power Transfer Switch between my grid line to inverter and direct to house breakers so if any issues with inverter I can easy change grid to go off or direct to house breakers. One think have bother my main: If grid is switch to house breakers and if not ac out on inverter is disconnected first from house breakers then will the inverter be back feed with grid power? I guess that's not wanted. I do have plan for breaker on ac out to.. Pink Link to comment Share on other sites More sharing options...

Pink Maybe i should use this one if back feeding is a issue: If i use 2 in for grid and 1 in for ac out (inverter) then ac out power cut together with grid cut from inverter.
