Jak nepostavit FVE (Zlaté Hory)

[Soban]

Tak další upgrade elektrárny......

Byl zprovozněn ten starý měnič REVO který bude používán jak svítí tak bude napájet bojler a zásuvky v koupelně a ven na zahradu.

V zimě bude vypnut a okruhy přepnuty na DS.

Tak vše je zapojeno, dnes kompletní provoz z DS elektrárna vyrobila pouze 1kWh a ta šla do prázdné baterky.

Tak jsem si s tím taky hrál, a zjišťoval kolik proudu berou ty vypnuté měniče.

Takže když je vše vypnuté a odpojené AC IN tak spotřeba je obou 130mA. (Měřeno BMV712 zkontrolováno i normálním měřákem.)

Jinak:

Zapnuté AC IN + zapnutý měnič a vypnutý jistič AC OUT čili nulová spotřeba:

MUST s vypnutým šetřením proudu - 1.35A
MUST s zapnutým šetřením proudu - 0.80A až 0.89A prostě to skáče ta poslední číslice a šipka na LCD do zátěže bliká prostě jednou je a jednou je jenom čára.

REVO nemá žádný šetřící režim, takže při vypnutém jističi AC OUT spotřeba 1.03A .

Dobrá volba teď budeš zase o něco svobodnější Pojede bojler a k němu třeba pračka. Mám taky doma v podstatě 2f rozvod z měničů. Jak jsi řešil AC IN? To musím ještě dořešit... vede mi tam 2,5mm2 pro oba měniče zatím jistěných 16A jističem. Plánuju tam asi dotáhnout další fázi z DS a každý měnič mít na svojí fázi přívodu.

[Soban]

Tak já AC IN mám na jedné fázi s 25A jističem, elektroměr a do obou měničů 4mm2 drátem.

Což je 25*230=5750W což by mě mělo bez problémů v bypassu stačit.

Z toho mustu mám elektroměr a taky 25A jistič aby to přetížení zvládl a za tím přepínač FVE - DS a už další rozvody taky 4mm2 drátem.

Z toho REVA mám zase elektroměr a jistič 13A drát 2.5mm2 a jenom na ruční přepínač FVE - DS a chráničojistič a šup s tím do koupelny, tam je podružný rozvaděč, s proudovým relé co odpíná bojler při zátěži ze zásuvek a soumrakový spínač který odpíná bojler navečer aby nežral baterku. Zde se nepočítá s přetížením proto tenčí drát a jenom 13A jistič.
Je to tak proto že do koupelny vede pouze jeden kabel 2.5mm2 - prostě se s bojlerem nepočítalo, byl tam plynový ohřívač.

Další kabely byly dány do lišt ať to trochu lépe vypadá.....

A druhý měnič - REVO

REVO

Kdy zrenovuješ dveře a obložky?

[Soban]

Až naprší a uschne

Vchodové dveře a střecha je spravená okna taky, elektrika částečně (ve dvou pokojích a komoře zůstal ještě hliník) vědět že budu dělat FVE tak bych dal největší rozvaděč a natáhl další kabely do koupelny pro bojlery...

Teď to chce zateplit, vykopat plynové topení a udělat nové, ale na co? Peletky a zdraží peletky a zlevní plyn jak to udělám, elektriku - to zase FVE nedá v zimě kdy to je třeba........

[TomHC]

Kdy zrenovuješ dveře a obložky?

Načo, to je teraz moderné

[glottis]

Dobrý termín je taky "až bude fve hotová"

[bokser01]

Docela mazec jak to Revo i Green cell jsou o dost menší než MUST. Asi tím vzniká odpověď která je v rozdílu kvality kde MUST je jednička oproti těm 2 jmenovaným.

Tady ještě když jsem měl Green cell a je pěkně vidět velikostní porovnání s MUST.

[Soban]

Tak MUST: Nová verze.....
(W*H*D)
272x355x100 mm

REVO: Je větší........
(W*H*D)
285x360x118 mm

Tak nevím podle mě v té velikosti není moc rozdíl......

[bokser01]

Aha, tak z toho co jsi postnul je revo opticky rozhodně menší

Green cell:

rozměry:
320.5x224x95.1mm

MUST:
272 × 355 × 100 mm

[Soban]

Tak jsem zprovoznil ovládání toho 24V mustu z Raspberry Pi 400 pomocí Node-RED.

must - ovládáí

Připojeno je to přes USB káblík, uvažuji k tomu připojit ještě revo a mppt od victronu.

Gratuluji, taky bych si někdy chtěl tuto statistiku zprovoznit

[Soban]

Tak já nic nikam neukládám, jsou to pouze živé data, ale není problém je někam do databáze ukládat a pak zobrazovat grafy.

[Soban]

Tak konečně použitelná verze se vším co potřebuji, dají se i nastavovat věci, prostě náhrada nepoužitelného programu co k tomu dodávají....

A aky je tam HW / procesor, frekvencia, SSD disk / a aky SW ? Aky Linux ?

[TomHC]

Nodered, to funguje aj na kalkulačke...

[bokser01]

Máš to moc pěkné... Mohu se zeptat čím to že ti sedí napětí MPPT a nabětí BATT úplně na chlup? kalibroval jsi? Já mám rozdíl mezi PV BATT a položkou BATT i 0,9V a potřeboval bych to nakalibrovat.

Tak kalibrace mi nechodí, prostě do toho registru nic nezapíši co jsem skoušel, nevím ani jaké rozpětí to bere, moc jsem to nepokoušel není třeba.

Jinak taky se mi rozchází ty napětí, ale to bych fakt neřešil, nastavení jde po 0.1V takže si nastavím tak aby to na baterce bylo OK.

Jinak HW jak jsem psal Raspberry Pi 400

V jednom USB je HDD - běhá to daleko svižněji jak z SD karty - ta tam není.
V dalším USB je káblík od měniče.

Jediné s čím je problém s rušením přenosu chce to kvalitní káblík a táhnout ho co nejdál od jiných vodičů.

[bokser01]

Taky mám Raspberry Pi 400 a s rušením jsem taky bojoval a nakonec vyřešil. Nedošlo k výpadku dat přes 3 měsíce po úpravách co jsem provedl. Jedu přes USB, koupil jsem 5M kabel stíněný (měl jsem i 2m stíněný ale přes něj to vypadávalo) Rušení se vyskytovalo nahodile při vysokých výkonech i po 5M kabelu. Následně jsem nasadil feritové kroužky hned u měničů a u vstupu do Raspberry. Od té doby to funguje skvěle a spolehlivě
