What kind of batteries are used in solar street lights?
Nowadays, LED Street lighting is a fresh new alternative to traditional street lamps such as LPS, HPS, or MH Street lights. Also, it provides a multitude of advantages over a conventional incandescent light. Moreover, LED Street lights are environmentally friendly, energy efficient, and cost-effective. Solar lights can use a different kind of battery such as Lead-acid battery and SMF
, lithium-ion battery or Li-ion
, lithium-ion battery phosphate or LiFePO4

What is the relationship of killowatt hrs and amps and 48 volts
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.

Why would I have a reading of pgrid na on my solax inverter.
It looks to me that the Power Grid is not connected to the inverter. Some inverters are intended to feed the grid, and if that is not detected, it will not produce power. If you want an inverter to work as an AC power source when the grid fails, then what you have purchased is the incorrect unit.

Hi I'm Sibongile Mokeki
My question is ...can I register meter number onli
*** Following is for PV solar monitoring.***
* Check your warranty. Call your Solar PV installer service. (or the salesman)
* Advise them that you need instructions and password to log into your solar monitoring account. (They should have set it up for you and sent you an email with your account link and password.)
* Once the account is set up you only have a short time period (about 2 weeks) to log in and register (or confirm) your account information. ( I requested 3 times for an account reset as the passwords would not work.)
* The problem is that you don't know when the I.T. (Information Tech) will get around to setting up your account. Get with the sales person to get the IT guys on the ball.
* You need to log into your PV monitoring site. (with password) and once on then bookmark this site and keep the account and password on save mode. Then it will be auto log in when you pull up the app to monitor your solar output.
*** The following is for Digital Metering for Home power meters. (not PV)***
* If the Electric company switched out your old analog meter (spinning wheel) with the digital display type then you have a digital meter. There are two basic types.
* The first type is a basic digital meter that keeps track of your power usage. It does not allow reverse power to be sent back to the grid. (well it can't prevent it but it does not record it for your credit.) This was designed to allow the meter to be 'read' at the company's power monitoring stations. This way they did not need the 'meter reader' to stop by your house every month. Remote monitoring (by customer) may or may not be available to the general public. Though the customer can easily read the displays on the meter.
* The second type of digital meter came after the need to monitor the power used and the power sent back to the grid. The meter is required to keep track of daily power and send this information back to the utility company for processing the electrical fees to the customer. The utility company also monitors and records the power return and calculates credits (if any) to be returned to the customer (not in case but as credits that are deducted from monthly bills.)
Note; Not all return power is accepted by the utility as there may be restrictions on how much or at what time period the power is sent back to the grid. Rates apply for restricted times or amounts.
* Contact your utility for specific information on rates and fees.
*** Check your utility bill for more information and contact phone numbers.***

If i add 2 or 3 solar panels will it overcharge my battery
Yes very probably and it might not do the solar panels much good either.
When the solar capacity exceeds or could exceed the demand it is very desirable to fit a solar charge regulator, solar voltage regulator or solar panel controller.
Many are available at all price ranges from beer-money to mortgage and both Amazon and ebay provide a wide range though it would be wise to gather some specialist knowledge before you buy.
