If a solar system is on a 48 volt dc system how many amps or killowatt is needed to charge batteries of 3,55 KW to full capacity with how many watt PV panels ?
Solar system? Did you mean "solar panel system"?
Unfortunately, some of your other terms are also a bit off. But let's see what we can clarify.
Battery capacity (whether a single, or a bank of batteries) is measured in kilowatt hours. A bank that is rated for 3.55 KwH will produce 3.55 kilowatts for one hour (at least in theory), or 10 watts for 355 hours, or any combination therein. The average home draws about 1.5 Kw (that's *average* - day and night), but much higher during the day (electric lights, appliances, etc. all turned on). So, very roughly, your battery bank is good for a couple of hours of average use - but might handle a home all night with minimal draw.
Sorry, but your final question is not answerable. A 48 volt system is 73 amps to do a full recharge during an hour. But that's too high a recharge rate for most systems. And batteries are not 100% efficient (figure on about 120% - or it will take about 4.25 KwH to charge a battery to 3.55 KwH. So the first issue is how quickly do you want the batteries to recharge.
Panel output varies widely (as does cost). And the amount of sunshine varies not only in duration, but also amount (an hour of sunshine on a clear day in Texas is worth more than an hour of sunshine on a clear day in North Dakota - although North Dakota may appreciate it more <G>). If you want to maintain the batteries, then figure on around 250 square feet of panels - but understand that this answer could be off by a factor of two or more - just depending on conditions.
SOURCE: What is the output in watts or amps of charging system?
The charging system is usually in amps. Consult your dealer or find the service amp output of the generator or alternator and determine
the amp draw you are using now, then add the 8.5 amps to it. For service live, do not exceed the standard rating.
Good luck,

DONT START THE CAR///IGNITION ON//PRESS THE GAS PEDAL DOWN 3 TIMES SLOWLY//THEN START THE CAR. THAT RESETS THE COMPUTER AND THE CHARGING SYSTEM WARNING LIGHT.

Golf carts do not have a charging system. If you are going to use battery power only, why not just add (1) 12V car battery instead of (2) 8V??
MA Audio runs (ran) their bench tests @ 17V. All the power ratings advertized are at 17V.
The power supply for the hk4000D is unregulated. So the more voltage = more power.. 8V-16VDC.
More input voltage means the amplifier will have to work less hard to make power.
Don't expect the amplifier to work for very long however. the current drain on a class D amplifier is huge. There are no on-board fuses protecting the power supplies, so be sure to have at lease a 150A power line fuse.
With 150A current draw - even with the amplifier at 1/2 gain - expect to get 10.6 minutes of listening time from your 16 volts before recharging - also note, the amplifier MUST see 8V to turn on, there is a built-in voltage sensor that will shut down the amplifier if voltage is too low.

You need to work out if the cost of two batteries is cheaper than a deal on a new drill pack

google the name and model #. The home website should come up in search. Go to site, and look in support, or replacement parts.
