So I had a little system installed about 3-4 weeks ago. One thing I’ve learnt is my calculations were very conservative. In any case, here’s my dilemma:
Bottom line, I’m not using nearly enough of my PV power. In fact, close to none. And I want to solve this. But not sure where to start…
Quick system overview-
4x 385W Panels (2S2P)
My system was meant to provide safe power, for in Pta East we’ve had regular power failures lasting hrs, days, weeks, it’s for a desktop (one of us works online) and a fridge, maybe a few lights, charger etc. And it does! Easily. I can run the desktop, fridge and washing machine all at once, midday, no probs.
At present though more than half of my power consumption for this rig is coming from the grid (see screenshot attached: “Consumption-17/06/22”) and this annoys me. Further complications are that we just don’t consume a lot of juice during the day, so it’s hard to add consistent loads onto PV’s production. Most consumption’s from the regular bandits…geyser (150L/3kW), old school stove/hob, nuke and kettles. So here are a few ideas I have, in no specific order, and most certainly open to critique and input, yes pls…
Cut ties with the grid by dropping the switch on DB breaker &/or AC-in on my installation’s AC combiner box.
As above, and should need arise, add another US2000C.
Somehow, somewhere, (and I haven’t figured out how) drop the % of use from the grid via the Remote Console, ESS thingy.
Here’s a nifty one…I have an extra unused geyser, 80-100L?, perched on the studio roof, the wiring/thermostat got fried. I’m wondering if I could insert a 1kW element and use the PV to fire this baby up, then no longer use the 150L. Does this sound doable?
It’s a smallish house with two outbuildings: Storeroom and Studio. 2pax. On the DB1 (main house) there’s an “Outbuilding” breaker going to the Storeroom. The storeroom has another DB2, from here 2nd fridge, lights/plugs for two buildings and possible Studio-roof geyser, plus overnight lights in yard.
The installation AC is currently not wired back into DB1 but has a plug adaptor attached from Multi AC-out (via AC Combiner Box) that feeds the fridge/desktop. Wiring AC-out back into DB1 and linking other plug/light breakers there to feed off the installation is also an option, but hardly any load will be drawn from them which, I suspect, will simply continue the trend of leeching off the grid and PV lying dormant. Though I stand to be corrected on this.
I should add that on DB1 there are three Plugs breakers, 1 for the house, 1 for the kitchen (hence fridge on adaptor) and a 3rd, I’m guessing it’s the unused/disconnected underfloor heating. This 3rd could be an option, except we have a double volume pyramid shaped interior, underfloor heating will do diddly squat.
I understand that it’s hard to explain to, or inform strangers of, one’s system, house set up etc. So any further info is at hand, just ask.
For me, in my ignorance, the simple solution would be to sever ties with the grid, temporarily, and incrementally add on appliances to use the system. Should I find myself in a pickle I can turn the grid supply back on. So I must ask, “Is there any technical reason to not do this?”, as in…
“Oh my God Cattus, you’ve broken the internet!!”
“But how? I just flipped a switch”
“Well, because of TPdTT feature, with it’s non-phased 01:3* factor lay-over feed-on/feed-through optimiser resort protocol, and the ESS bindback multi-dip excess log you’ll not find Scarlet’s love no more.”
Thanks for reading my ramble.
