Hello from cebu cty, philippines.

[jadd allestair]

I'm still planning to set-up may solar panel here at cebu planning to set-up a 2kW grid tie system.
I will be asking lots of questions.

First on the list.
1. I already have a XANTREX C60 charge controller, can i use this unit in a 2kW PV array with a 24volts system?

Thanks.

Hi for a grid tie system you need a grid tie inverter. there are no batteries used in a grid tie system. Tere is an exception under certain circumstances you can use a hybrid inverter specially designed for battery connection and to the grid.

In Phils you will not be successful in having a GT system as there is no net metering. This means all excess power you generate from your panels will not be sold back to the power co. but in fact your meter will show that power as used by you and you will be charged for it.. In simple terms your meter is your enemy. It now shows what you use from the grid and if you use grid tie it will add that to the meter reading and you be paying for what you generate.. BAD DEAL.

It makes no difference really if you use a hybrid system so you can have power when the grid is down"brownout". But you be wasting your money on the batteries as they have to be replaced every 4 to 6 yrs.

I know electricity is expensive in Phils but its more expensive to try do anything about it.

Thanks for the advice.

I should consider off grid system in that case.
If I'm going set-up an off grid system and I already have a XANTREX C60 charge controller, can i use this unit in a 2kW PV array with a 24volts system?
Sorry for asking this question again need to clarify this inquiry so not to spend another peso in setting may off grid system.
Thanks

its max continuous rating is 60a
60x12 =720
60x24= 1420w
So the max wattage it could be used with on 24v is 1500w of panels..

But why you want to go off grid?? You certainly wont save money.. The cost of replacement batteries every 4 to 5 yrs will cost far more than the electricity you will generate.
Add to this the cost of the panels and . you are losing a lot of money.
Sell it to some other unsuspecting buyer.

Is there any chance i can use this C60 in may 2kw system with out damaging the unit?

I'll be using a 4 -12V 200Ah Motolite sm200 battery - Locally available deep cycle battery here in CEBU with free delivery.
10 - 200watts 12V Top Solar Panel200 (connected in 24V)
Inverter 2.5kW (should be 240V/60Hz) preferred brand xantrex - can anybody recommend a model with the stated specification?
C60 Charge controller - any other option so that i can use it in may system?

Required electrical system (Philippines):
240Volts/60Hz/1Phase

Only way to use 2 Kw of solar panel input with a 60 amp charge controller is to operate at 48 volt battery. No ifs, ands, or buts...

[Sunny Solar]

This whole idea of using grid tie in Phils is useless. NO NET METERING. Everything you generate is going to go through the meter and you will be charged for it.
Example.. you use 600kwh for the month from the grid you generate 30kwh you dont use ,your electricity bill will now be 630kwh.At about p12 per kwh ,so now you pay another p360 to the power company..great huh??? And this is not about to change anytime soon.

this is where an inverter such as the XW series Xantrex come in. you can program it to not sell back to the utility and either load shift load shave etc.

[jadd allestair]

guys i truely appriciated all your support, problem is the C60 i have right now is of no use?
with the 2kw system that i computed for may house hold use.

any advice for the charge controller and inverter unit that are capable to handle the 2kw system.
at 24 or 48 volts system preferred brand is xantrex.

[Sunny Solar]

Well you need to look to the XW series of Xantrex as Naptown advises.
Just be very sure whatever inverter you buy does NOTsell back to the power company. or you be paying for what you give them,,

[jadd allestair]

Guys can you give me a link or model from xantrex with the specification below i have try to look but with no luck.

Brand: Xantrex
Voltage: 220-240Volts
Frequency: 60Hz
Capacity: 2.5-3.0kW

I have look at this model TR2424-230-50
but the unit is 50Hz what will happen if i plug my 60hz LCD TV or any equipment with 60Hz frequency?

Thank you in advance...

Xantrex XW 4024 or XW 6048

[jadd allestair]

XW model is very expensive.
any other option? price range from 6-15 hundreds.

Is it ok to use the XW4024 with 2kw PV array?
or there will be problems in the effeciency of operation for the inverter.

Need clarification regarding this model.
Model TR2424-230-50
Unit is operating in 50Hz what will happen if i plug my 60hz LCD TV or any equipment with 60Hz frequency?

It depends. Some computer and other electronics power supplies are listed as working from 50 to 60 Hz and from 100 to 240 volts. They can do that because they are just using a switching power supply to produce DC that the electronics needs.
But if the TV or other equipment states something like 60Hz, 110 to 130 volts, for example, it may work badly on 50 Hz, and even burn out part of the power supply.
Motors and gearing designed for 60Hz will turn slower and probably consume more power. For some uses that will not be problem. Larger motors such as an A/C compressor will have problems.
