Solar panels, inverter and battery question

[@offroad]

Depending on your inverter specs, one thing you may want to tweak is to use 8 panels instead of 4 (keeping the wattage the same) as this will keep the MPPT above the minimum startup voltage for longer in low light conditions.

Just be aware not to overrun the max open circuit input voltage (Voc) of your inverter though.

Can't edit this but what I meant was to keep the total wattage the same for both the 4 and 8 panel ie the 8 panel solution would use panels half the wattage each of the 4 panel solution.

Ek het gevind daar is 4 stelle koste vir my stelsel min of meer dieselfde, inverter, battery, sonpanele, instellasie - as jy 3 uit die 4 gaan doen sou ek aanbeveel dat jy erenstig kyk na panele jy gaan mos ook 25% afslag daarop kry. As die son skyn gebruik jy sonkrag en laai die batterye en rekening minder- dink weer.

25% discount, my arse!

“I hear that Kodak inverters are Sh%t” , “I hear they don’t work well” , “Someone told me I should stay away”. These are the things I hear on every second…

Why do you say this? I've found that when properly documented SARS honours their obligations. I was able to deduct solar expenses when I worked from home based on % of house taken up by home office, you have to spread claim over 3 year period. If you plan to go this route you might as well provide them with all the documentation when you submit your tax return. The 25% to a maximum of R15k is generous for a residential installation.

Thanks for that.

Written by a CEO, so not much technical, which is fair.

A little warning light is flashing in my head, though, where he says you need protection on the incoming line to deal with fluctuations. I can see why it may be needed, if this is an off-grid inverter, and it may very well explain it's bad rep.

Like most today, though, I'd expect a plug and play inverter, that can do it all. The inverter should have self-protection that monitors voltage as well as frequency.

What sort of inline voltage/frequency protection can you get for R1K?

Anyway, as someone who hates spending money on necessary evils, I'd still be attracted by the price of the inverter .........................

Question

I currently use a induction plate (Midea Slim Sline Induction Cooker 2000W) to boil my kettle.

Will an induction plate still be energy efficient with an inverter and battery? Or am I better off putting it on the gas hob then.

Google has mixed answers.

2000 watt is big ..if it uses the 2000 all the time its on .... if you running 3.5kva which kind of equals vaguely 3500 watt in my understanding... while cooker is on u using more then 50% of your output ...

Use gas to boil your kettle during loadshedding.... winter's on it's way, so you warm the room up at the same time!

From other forums; Certain smaller inverter have difficulty driving the induction cooker if for instance you halve the load, say 1000w the cooker apparantly achieves the lower load by pulsing. I never has a problem using an induction cooker with my Goodwe inverter during LS, especially if the sun is shining, even at night used accidently by my wife it still worked fine.

I presume the OP has evolved into a 'general' discussion on the topic.

I was hoping to get some input. I received the following quote and I would like to know if the pricing is in line with what is out there.

Thx

Baie dieselfde as wat ons het, en heeltemal in lyn.

2000w is 2000w. And that's a lot, a kettle is usually +-1200-1500w. With Solar I recommend kettle on gas stove.
Of course, if you have the sun to spare, and your inverter can handle it, then 2000w is fine.
