I have a Luxpower SNA and Shoto 5.12kW running for 3 weeks now. Some initial minor issues that a firmware update resolved quickly. eg. Inverter picking up that the battery is a 50ah, not charging the battery. The default settings also had to be tweaked slightly like changing the charge voltage to 56v from 55. All running as it should. Regards Delwin

Hi, I've recently installed a Luxpower inverter with Shoto battery. All good. We decided to install an automatic transfer switch to bypass the inverter when the grid is up. I prefer this as I don't want to be limited to 5kW draw when the power is on. Considered taking off loads, spitting DB, etc. Anyway. The ATS installed has a relatively quick transfer, but long enough that the wifi and TV reset. Quite irritating. I was wondering if one gets an ATS that has a transfer time similar to that of the inverter (10-20 ms)? What about something like this (see below)?

@Scorp007 Thank you for this.

My understanding is that a grid-tied inverter will not work if there is no grid supply. Not a biggy. Will a hybrid inverter work?

@liceman Yes, they are rather expensive. Around 20K. I think my idea would cost less + I don't have to change my pump.

@JayN Yes, exactly that. Thank you.

Okay thank you. I would like to use without the battery yes. Then this one then: https://ecopec.co.za/product/solis-mini-4g-single-tracker-inverter-2-0kw/?utm_source=googleshopping&utm_medium=shp&utm_network=x&utm_mobile=0&utm_creative=&utm_position=&utm_random=759919814526010837&gclid=Cj0KCQjwhsmaBhCvARIsAIbEbH5Pcr_ivOAW8Q4WQZoqMlDbXcSv9WEHvIhiQp8ZUt0pmL_N3CFrEdsaAqjQEALw_wcB&utm_campaign=smart shopping - za (3)&utm_ad_group_id=984757&utm_campaign_id=1025688&utm_prod_id=5628

Hi smart people, I need some advise please. I would like to run my pool pump off solar, with the grid supply as a backup or to cater for shortfall. I don't want to use batteries. Only solar. Inverter will be connected to the pool pump DB. Herewith my idea: Existing pump spec: Speck 1.1kW Operating Watts: 1085w (Tested) Start-up watts: 1630w (Tested) Proposed Inverter: Growatt 3000w. Max PV array 1500w. Max open circuit voltage: 102VDC. MPPT range@operating voltage: 30-80 VDC. https://www.solarwaysuppliers.co.za/wp-content/uploads/2014/01/GROWATT-PDF-NEW.pdf I WOULD APPREICATE ADVISE ON AN ALTERNATIVE INVERTER. PRICE RANGE R5000-R8000. Questions: I'm thinking of getting 3 x 450 watt panels. Is that enough? What do I need to look out for? Can the proposed Growatt inverter operate without batteries connected? If the power generated from the panels doesn't meet the full pump load. Can the balance be taken from the grid? I assume the motor start-up can be powered by grid and then switch to solar for operating power? Any advice would really be appreciated. Thanks in advance Delwin
