Products Enphase Energy

an enphase m190 mounted , grounded.

all enphase microinverters same internally, differences in maximum amount of power can handle , cabling system being major differences between models.

legacy products

the m175 first product, released in 2008. designed output 175 watts of ac power, capable of 5% on that. m175 packaged in relatively large cast aluminum box, similar boxes used on cable tv amplifiers seen on telephone poles. wiring passed through case using compression fittings , inverters connected each other using twist-lock connection. limited number of m210 models, based on same generation system, available limited time.

due high level of failures m175 recalled , replaced m190 in 2009. m190 offers higher power rating of 190 watts (peaking 199). system packaged in smaller case, time filled epoxy potting material handle heat dissipation, , built-in cable connections replacing earlier compression fittings. system otherwise similar, using same connectors , cabling m175, , 2 designs mixed in string. predecessor m175 m190 has been plagued high failure rate.

around same time company released d380, 2 m190 s in single larger case. small inverters m190, case , assembly represents significant portion of total cost of production, placing 2 in single box cost spread out. d380 introduced new inter-inverter cabling system based on drop cable system. placed single connector on short cable on inverter, , used separate cable either 1 or 3 connectors on it. arrays constructed linking 3 d380s single drop cable, , connecting them other drop cables using larger twist-fit connectors.

current products

in 2011 entire lineup replaced 3rd generation m215, combining features of m190 , d380. m190, m215 single inverter, in smaller box. d380, m215 used trunk cabling system short connector cables on inverters. however, instead of 1 or three-drop cable, m215 s engage system, used long roll of cables connectors spliced it. installer cuts engage cable required length, , caps open ends result.

in 2013 m250 released, offering new grounding system eliminates otherwise nec - required external grounding conductor, increased reliability, , increased efficiency (96.5%), along rating bump 250w. whereas previous models named after maximum power rating, m250 refers peak power. using same convention m190 called m199. m250 otherwise identical earlier m215 , compatible same engage cabling system.

all enphase models use power line communications pass monitoring data between inverters , envoy communications gateway. envoy stores daily performance data year, and, when available, allows enphase s enlighten web service download data approximately every 15 minutes. customers , installers can review data on enlighten web site.

in 2015 company launched fifth generation of products. s230 , s280 microinverters have highest efficiency module-level power electronics @ 97%, offer advanced grid functionality reactive power control, , comply regulatory requirements electric rule 21 in california , rule 14h in hawaii. next-gen envoy-s offers revenue-grade metering of solar production, consumption monitoring, , integrated wi-fi. company moved home energy storage storage system featuring ac battery, modular, 1.2kwh lithium-iron phosphate offering aimed @ residential users part of home energy solution. home energy solution launch in australia in mid-2016.
