meron po ba nabibili grid tie inverter sa raon?thank po sa sasagot
Positive grid corrosion
Bad news... bumigay na ang 100AH solar master ko... palagay ko ay "Positive grid corrosion" ang sanhi ng pagkamatay niya... nakita ko na dalawang butas ay nagku-kulay itim kapag charging... mabilis na siya ma-full charge pero hindi na niya naho-hold ang charge at bumabagsak na sa 10.7V while resting indicating na sira na ang isang cell... umabot lang ng 2 years at 11 months.

ganyan din sir nangyari rocket 100ah battery ko ng biyakin ko, binili ko online olx, used telco battery, good as brand new daw, kuno, di na mag hold 12 volts, 10.9 volts na lang halos tumagal lang six months, wala na warranty, babay na..View attachment 293325

tuwing brownout lang gumagamit ng total 139W para sa desktop pc with printer and internet...apat na 4W 12VDC LED bulbs pag-ilaw magdamag (6PM to 6AM)... ang charging panel ay 160W with 20A Epsolar PWM scc... marami na akong nababasa dito sa thread ni ma'am TS at sa SolarPowerPhil FB group na ang pinakamadalas na dahilan ng pagka-sira ng solar master battery ay positive grid corrosion (umiitim ang electrolyte)... meaning medyo mahina ang pagka-gawa ng plates ng battery (hindi madikit ang lead oxide sa positive plates)... napaka-swerte mo na at sulit na kung umabot ng 3 years.

Mga ma'am/sir tanong lang po,
-ano po ba talaga pinagkaiba ng lead acid sa Li-ion(18650) na battery?
-ang 40Ah lead acid po ba ay directly equivalent sa 40Ah Li-ion battery pack/assembly?
-pwede ko po ba magamit ang isang Li-ion pack/assembly as replacement sa lead acid sa system ko
w/o changing anything else?
salamat po.

nakasubok na rin ako gumamit ng lithium laptop powerbank... hiwalay ang output nila (usb, 12V at 19V) at meron na built-in battery management system (BMS) circuit board... nabili ko ng 2.5K sa lazada... inabot lang ng 1 year and 6 months.
mahirap maghanap ng lithium battery na 12V... karamihan ay nagdi-DIY lang, kaya lang ay mahirap makahanap ng BMS board atbp parts and components... at kailangan mo pa ng spot welder.
ang charger ng lithium battery ay iba rin... hindi pwedeng gamitin ang charger na para sa lead acid battery...
mas madaling gamitin ang lead acid battery kaysa sa lithium battery.
