hmm para siyang i-Panda. SCC and PSWI inverter/charger in one.
It doesn't appear to be a grid tie.

similar to the PowerStar LF inverter it can be setup like a Automatic Transfer Switch once the battery level goes down. (as far as i can remeber may feature siya na ganun)
it can chrage the batts via AC as well.

ang maganda sa kanya yung charging function.
pero gusto ko malaman yung ibang components.

i wont spend that much money on something that has no info.

kaya for now, dun pa rin ako sa individual devices.

i am still hopeful na may readily available na hybrid system. wala e. gusto ko grid tie but charges the battery first (with limiter or may option not to export)

Sir glennjv… Ah ok, so lumalabas na re-brand siya ng “i-Panda. SCC and PSWI inverter/charger in one”… kaya pala alanganin maglabas ng detailed information… baka kasi may mag-reklamo for violation of “intellectual property” blah blah… anywayz, at least pasalamat pa rin tayo kay da king sa pagiging available ng isa pang bagong solar power technology sa Pinas… dapat sana ay huwag nang ipagbawal ang pagpapalabas ng mga new technology information para hindi tayo nagiging kulelat sa mga bagay na ito…. Sana man lang ay tumulong ang gobyerno para makapasok iyan sa Pinas sa murang presyo.

Alam ko na ngayon kung bakit parang nakaka adik. Palaging kasing iniisip kung paano pa mapapababa ang electric bill.
Next project off grid ng lightings. Konti pa lang nabawas ng aking bill.

Humahataw din ang aking maliit na setup.may load yan na isang 15w 12vdc fan.. float charge na kaya yan mga ka solarholic? Bumababa ang voltage. Pang fan sa umaga at at dalawang led strip naman sa gabi.. reserve ko sa gabi ang 100ah na battery.

- - - Updated - - -

Nagkaroon ng corrosion ang aking 100ah battery. Niliha ko lang ang positive terminal at connector

.. float charge na kaya yan mga ka solarholic? Bumababa ang voltage. - poseidon

... as per experience, kapag umabot na ng 14v+, tapos biglang bumaba sa 13v+, ibig sabihin ay float charge na... pero kung hindi ka pa umaabot sa 14v+, hindi pa sya float charge.

"3 Stage charging voltages look something like Bulk = 14.1, Absorb = 14.7, and Float = 13.2"

Nagkaroon ng corrosion ang aking 100ah battery. Niliha ko lang ang positive terminal at connector

... sumisingaw ang battery electrolyte mo... baka masyado mataas ang level ng electrolyte?.. sa akin kasi going one year na, wala pa rin corrosion.

@poseidon
Ilang watts yung nakalagay sa 17AH panasonic battery mo?
San nakakabili ng ganyang led? Magkano?

Dami na bago�� ah.

Hindi na sapat yung battery 8 and 7.2 AH ko nauubos na kahit cellphone charging lang... ��

 

[poseidon]

17ah at 30W panel sir. Kaya ng setup na ganyan ang isang 15watts 12vdc fan. Hindi deficit ang charging basta maganda ang sikat ng araw. Yung led strip nabili ko lang ng Php40/pc sa motorcycle shop..

@ Poseidon "Nagkaroon ng corrosion ang aking 100ah battery. Niliha ko lang ang positive terminal at connector"

Corrosion of the terminal can have several causes:
- your battery is often overcharged... very bad! You monitor closely the charging!
- the battery is in a humid environment or there is a great difference of temperature between day/night
- the copper wire is bad quality
- there is a defect of the battery at this terminal which let pass some acid

In all cases, you need to clean up properly the terminal with an iron brush and sand paper and then apply some Petroleum Jelly.
The current does not flow properly thru a corroded terminal!

... naka parallel connect ba two batts?... less than one year pa lang bumaba na ang capacity?... dahil kaya sa hindi equalize ang mga battery cells kasi magka-iba sila?... ma-revive pa kaya sila kung equalize charging separately?

try to charge my 100AH solar master with panther 7 stage 10,000mA (10amp) battery charger
battery reading before charging (12v) almost 50% left,
using Omni watt meter nalaman ko how much ang electric consumption ko using AC battery charger,
turn on the panther battery charger , omni watt meter reading for panther battery charger watts consumption 155w to 160w
once na reach na 14.20v , maliit na watts consumption ng panther 55w na lang hangang ma fully charge
total kwh consumption for 11hrs and 40min ( 1.2kwh) omni watt meter

Baka nasa crimping ng wire at ng ring connector ang problema. Hindi rin naman siguro madalas na over charged. hirap pang makapuno ang aking panel sa sa aking setup na 100:100. 20w lang load ko magdamag pero hindi pa ako umabot ng 14.7volts sa charging. Nalinis ko na rin naman kaso hindi ko pa nalagyan ng petroleum jelly. Baka papalitan ko na rin #guage 10 ang mga wire from panel to scc. 12 lang kasi gamit ko at medyo may kahabaan. Naka parallel lang ang 2x50Wp sa #guage12 na wire.

Thanks... that's interesting to know for people who need to recharge thru charger... but seems to me it's a lot of electricity 1.2 Kw to recharge 50 amperes...

oops... your wires are really 2 small! Change them as soon as possible as you may end by damaging your setup!

sir dmb101... ano ang pipindutin para makita ang "total kwh consumption" sa omni watt meter... nawala na kasi ang manual ko.

assuming na P10/kwh... P12.00 lang ang gastos mo para ma-charge ang 100AH battery... matipid pala ang panther 7 stage 10A!

… sir dmb100 are you trying to tell us that it is CHEAPER to charge a 100AH battery by using AC battery charger rather than by solar panel?... (as proven by the omni watt meter)… do you want to ask if we agree or not?

mam yung sa akin,meron akong akong apat na mahabang no.16 stranded wire,yung 4 na stranded no.16 ginawa ko lang dalawang linya,para sa 100w panel

Yes, even 4 x #16 it's too small and not good at all to have this kind of wiring... dapat solid wire #10: it's safer and you will not have a loss of current... with your wiring, your panels cannot charge properly your bat because of the loss in the wires...

mam yung extension double wire na no.16 kapag pinag isa ang dalawa ay magiging #awg no.8 na,plus yung isa pang stranded wire no.8,kapag pinag isa ang dalawang no.8 ay magiging #awg no.4,kaya meron akong dalawang #awg no.4 na wire para sa dalawang linya,tama po ba?kung solid wire ano pagkakaiba nito?
parang ganito;
2 wire no.16 x parallel connection=no.8
2wire no.8 x parallel connection=no.4

... nabasa ko sa foreign forum, bawal daw sa electrical code ng USA... hindi raw aprubahan ng inspector... fire risk daw ang reason.
