Equipment selection help

[JeffL]

I put a modest system on my house last year and landed on mostly Schneider equipment for a number of reasons and am quite happy with it for that application. Now I’m looking for a much smaller system to power a greenhouse. The overall power needs are much smaller but there are large induction motors at play one of which is 240v. So I do not need near the power storage nor the KW peaks on this system but I do need the inverter to support both 240v as well as be able to handle the tough start up of the motors.

In addition I want a hybrid inverter that can prefer the DC power when available but auto switch the AC as needed.

I’m trying to find an inverter in the sub $1200 range. Any one with experience with similar system parameters and knowledge of quality equipment that can do the job I would appreciate input. Initial window shopping has me looking at some of the sungoldpower products but I know nothing of their longevity or product support so nervous. Near as I can tell Schneider does not make a product in this smaller system niche.

Many thanks

What's the LRA of the 240V motor?

 

[JeffL]

I’m not at the location to check the exact motor but googling for a similar fan is showing 20-30 amps.

30A * 240V = 7200W surge

Run should be around 1200W.

I really think a detailed energy audit is in order.

Yeah looking at one of the 3 units it is more power than I thought at first. Just the greenhouse is light on power with some larger but not crazy large fans and a few led (not grow) lights. But I would like to consider being able to put the workshop's mini split ac on and that is around 2200 watts by itself. Which probably means I’m trying to size a system without the mini split and another without and then decide if the cost difference is justified.

Do you have objections to ordering from alibaba?

Not exactly, but quality warranty and support are high value to me so I suspect that rules it out .

You might want to do a bit of research on SRNE.
I'm coming up on 6MWh of solar through my ASF. I paid just under $1400 delivered to my door last fall.
I recently ordered 2 ASP for a parallel setup and paid ~$2255 delivered to my door in 10 days.
The ASF runs my entire house, including my deep well pump that pulls ~40A inrush, my mini split, electric dryer, etc.

The only thing I can't comment on yet is longevity or warranty, the few times I contacted support they were quick to respond and helpful.
Normally I don't make recommendations but it seems to be in the price point you are after and checks the boxes.
I have some threads with lots of additional info.

Anyone have experience with the Schneider SW 40xx inverter? In particular with how well it does with surge starts? It’s a bit more $ than I was hoping but having been pleased with support on my XW it does stay in the same family.
