At 39$ this is low watts and importantly low standby watts. 1.5w standing by!
i have had a couple versions of powerbright, 900w and 2300w 24v. They are reliable and clean
enough. Keep the fans clear and maintained.
If you want something nice. This inverter is an all around lighting and sensitive electronics winner. Reliable, efficient, clean.

Morningstar charge controls have been stellar. Use the pwms with appropriate modules. Under a hundred dollars for 20 or more years of service. The mppts are pricey but good. More flexibility with module and battery voltage.
A midnite
solar brat is a good hundred dollar pwm.
These are tanks. 120$ Not super adjustable but have wide pv voltage acceptance in a pwm controller that will switch between 12/24/48 volts battery systems. At 12v it will just take two 300w panels at higher voltage it does quite a few more.

For a single 12v sealed or pair of 6v golf car batteries it will have all the charging current a 250ah would want and then some.
Dc distribution and 5v charging.
The plate is just a plate but depicts multi 4.2a usb charger and cigarette lighter plug receptacle 12v power with battery volts all in a strip. The site is worth a look around.

A real pv module. Or two. Best 207 dollars you will ever spend on power for the small demand you are indicating would be one or two of these.

Have a good battery, sized overlarge by 1.5 to 2 times what the guideline is for your autonomy.
Doing this will alow the battery to age and still power your house for the design autonomy and for years longer most would
experience.
If you have the budget, shoot for 10 percent or less discharge overnight or even 24 hours, depending on major household time of use patterns. Or multiply by days of use without sun and limit at 50% dod and go 1.5-2 times.
Now that is a stout battery for home power. Charging capacity
should be your standing load plus as much gusto as the battery will reasonably allow.
Within 10 percent of battery max charge amps is a good place to be unless you have larger standing loads, then i use it all.
All systems are different and you may only require 1200 watt hours over a week, then this would be too much equipment.
Hard to beat a couple golf car batteries (or a sealed deep cycle 8d) and a 300w module or two, once you are at the trouble. Light always available, pressurized
water if you like, communications uninterruptable with multi voltage operation from a power supply with 4 major components or less.
