Based on the search results, it seems there are both new and second-hand generator options available. The Honda EU22I 2KVA Inverter Generator that I originally recommended is a top-rated portable generator known for its quality, reliability and low noise operation. It seems however that only spare parts like the generator air filter are listed in the search results. If you're open to a second-hand unit, the Refurbished Dell Inspiron 13 5000 Series Touchscreen Laptop looks like a very good value option. Refurbished units are a more affordable way to get high-quality tech products. This Dell laptop received a full refresh and cosmetic cleaning, so it should operate like new. The Intel Core i5 processor, 8GB RAM and 256GB SSD should provide plenty of power for daily uses. Please let me know if you would like me to explore either of these options or a different generator in more detail based on your budget and needs. I'm happy to help narrow down the best fit.
Yes, several of the generators in the search results can be used with solar panels. The Neo 1500W and 600W portable solar generators from Goal Zero are designed specifically for use with solar panels. They both come with integrated solar inputs so you can charge the generators from solar panels during the day to power devices and appliances anytime. They would be great options if you want a generator system that can be charged from solar. The EcoFlow Power Hub is also a larger portable power station that works with solar charging. It has a higher capacity at 3.6kWh. Let me know if you have a particular budget in mind and/or how you intend to use the system - I'd be happy to recommend some suitable generators and solar panel options.
Here is a suggested solar power system that could work well for your big home on a budget of R100,000: I would recommend the Mecer Axpert Maximum 8000W Pure Sine Wave Inverter listed for R20,389 as the centrepiece of your system. It is a high quality inverter capable of powering most appliances in a large home. To charge the inverter, I suggest combining it with the Mecer Infinisolar 15KW 3 Phase Pure Sine Wave Hybrid Inverter for R61,254, and supplementing it with a few 300W solar panels. This would provide reliable backup power from solar during the day, with generator support for nights and cloudy periods. It stays within your budget while setting you up with a durable, low maintenance system suitable for whole-home usage. The inverters' pure sine wave technology ensures compatibility with all your devices too. Please let me know if you need any other details.
