In Europe now there is power issues and also crazy prices on electric power ..I dont know what the chances for same issue here..but for me it was just another good reason to try get this project rolling. Even in the cold north Europe where im from they have waiting times of 6months + to get solar installed, so in this climate solar should be on every roofs. Pink

Thanks for that info, great pink

Ok thats for sure a issue. Pink

Yes i have think about 2 and also 3 inverters in parallel. And also the 11kw from Taiwan. Then i kind of end up with a plan where i can do this in steps without to large as first solar project: Start with a 5kv inverter and 4kw panels or so as step 1. The 5kv inverter could be the powmr 5.5kw ready for parallel and wifi. Then step to ad batteries. Then if or when want or need ad more inverters/panels/batteries. Pink

At that time of issue you was on ac power or battery? There is a 5ooo watt limit right? Pink

Looks like i have 2 lines already to main supply for the 2 heaters. so the plan must be to get rid of that 9kv issue by access them only to grid. Should i have a separate box for that? I guess the main breaker box feed same power to all breakers? Pink

I was plan to buy panels today then i just find a post in another tread about water heaters and all in one inverter not really a good match. I have 2 x 4500w showers.. So maybe then options is a grid tie inverter? or maybe the low frequency 48V 10Kw diy i post before then with a extra ATS to grid power? Pink

Thanks for that info.. I have 2 x 4500 watt showers. I forgot this when calculate my watt usage. So this kill the all in one options? Pink

If a inverter have max 500VDC what value on the solar panel is used to calculate the vdc? Pink

BritManToo how is the experience with your Powmr after some months usage? Pink

Looks to be a good unit. I see its about the double price of the cheapest 5kv units, so i guess its a high quality product with some support and warranty/service etc? Buying the cheapest stuff in some cases can be very expensive, Im all in to pay some more if the value, quality and life time is there.

4 x5kw all in one? how much panel capacity you would connected to i? Pink

Here is a estimate i got from a recommended trusted seller in China some weeks ago: --- For 16 cells EVE LF280K, the total is 16*110+458.7USD=2218.7USD, add 2.5% Alibaba fee. For 32 cells, the total is 32*110+896.7USD=4416.7USD, add 2.5% alibaba fee. --- The cost of the batteries more or less as expected , but the shipping cost is to cry off.. Pink

What is the way to connect 2 AC load cables (before connect them to house breaker box) from 2 Hybrid Inverters In Parallel ? Pink

https://powmr.com/manuals/PowMr-Manuals-Solar-Inverter-Charger-48V-220V-80A-POW-HVM5.5K-48V.pdf page 40 I see outgoing ac connected to same wire as i expected, so what i try to ask what i should use to combine this 2 ac sources to 1? Pink

Something like this? https://www.lazada.co.th/products/3-knife-switch-2p-3p-32a-63a-100a-i2047964700-s6660382746.html? Im going slow on this so im still not sure what to choose. And i need to know what i need etc before ask any here to help wire the AC cables from grid etc etc. But new tread coming for sure when im start ordering. Regarding If they are off-grid hybrids they will have a grid input, grid goes there. Inverter output goes to the house breaker box. The inverter instructions should show you how to add a bypass switch: the 2 inverter outputs connected together or output 1 goes to inverter 2 then output 2 goes to house breaker box? Right now its 2 x powmr 5.5kva ( parallel version) vs the 11kva Mppsolar.

Now i research a plan for 2 x 5500kv inverters in parallel: So if i set up a single line (all serial) to each inverter, and a battery pack to each inverter. So how to combine 2 x outgoing power from the inverters to House breakers box? Is there a good way to add a option for grid power to direct to breaker box if wanted or needed? Pink This will give a possibility for a step by step plan where i try out with one inverter and half of the panels first

Im happy to see your project progress and your inverter doing well. Im considering getting 2 of this inverter in parallel. Pink

When you calculate panels vs inverter would you limit panels to capacity listed on the panels even you just expect 50%? Pink

BritManToo can you share how you connected the panels and what parts you used? Pink

Yes i see same when compare posted prices few months back. Prices up around same level as your example. I also see most sellers and solar companies have very identical prices. Pink

Ok thats not to bad price. I thought first i find better price on fb marketplace Sunfree panels but then i found out price was excl vat. I see from their pricing price up 2 times last months. Looks like inflation affecting sola panel pricing. Can you share how you fasten then panels on your steel bars? I have some steel left over from some project so i will try make some diy solar rails with it. Pink

You got the panels recently? Where you buy panels ? And what panels you got? Pink

Your so fast to get it up.. Im impressed. What was J&T express excuse? I had same to me happened once too. Do you main explain why there is wire from inverter breaker box to house breaker box? How you feel the quality of the inverter? Edit: Or your intake is just under the house breaker box? Pink
