Nejd\u0159\u00edve jsem cht\u011bl za zhor\u0161en\u00fdch energetick\u00fdch podm\u00ednek (mal\u00e9 proudy) otestovat jak se syst\u00e9m chov\u00e1 p\u0159i dosa\u017een\u00ed pln\u00e9ho nabit\u00ed baterie, a t\u00edm nemysl\u00edm podle ukazatele SOC, ale podle skute\u010dn\u00e9ho stavu \u010dl\u00e1nk\u016f. Zhruba 2 dny baterie reportovala 100% SOC, ale a\u017e 3. den se dostala do stavu pln\u00e9ho nabit\u00ed. B\u011bhem n\u011bj se projevil z\u00e1sah regul\u00e1toru „shora“ i kdy\u017e asi zbyte\u010dn\u011b vysoko – p\u0159i mal\u00fdch proudech a pomal\u00e9m nab\u00edjen\u00ed to nevad\u00ed, po\u0159\u00e1d jsem se ve\u0161el do optim\u00e1ln\u00edho rozsahu nap\u011bt\u00ed \u010dl\u00e1nk\u016f, ale upravil jsem nastaven\u00ed na 55,2V nam\u00edsto 55,5V aby to ned\u011blalo probl\u00e9my, a\u017e budou sol\u00e1rn\u00ed zisky v\u011bt\u0161\u00ed.<\/p>\n\n\n\n

Nastaven\u00ed jsou u\u017e taky provedl „z monitoringu“ tak jsem si pro\u0161l\u00e1pl cestu, jak n\u011bjak\u00fdm agentem v p\u0159\u00edpad\u011b akutn\u00ed pot\u0159eby na z\u00e1klad\u011b dat z monitoringu mohu upravit parametry nab\u00edjen\u00ed.<\/p>\n<\/blockquote>\n\n\n\n

Na grafu je vid\u011bt aktivov\u00e1n\u00ed balanceru, a ku konci dne do\u0161lo k vybalancov\u00e1n\u00ed \u010dl\u00e1nk\u016f na rozd\u00edl 0,001V co\u017e je super hodnota!<\/p>\n\n\n\n

<\/p>\n\n\n\n

Pak, kdy\u017e byl jasn\u011b nastaven a zaktualizov\u00e1n stav SOC jsem se rozhodl otestovat, jestli je v baterii skute\u010dn\u011b 15,5kWh resp. s nevyu\u017e\u00edvan\u00fdma rezervama n\u011bjak\u00fdch 15,3 kWh. Zkusil jsem tedy vybrat nejhor\u0161\u00ed obdob\u00ed, aby spot\u0159ebu moc nedotovaly panely, ale aby jela prim\u00e1rn\u011b z baterie. Bohu\u017eel tip zas tak nevy\u0161el, a p\u0159es p\u0159edpov\u011b\u010f nep\u0159\u00edzniv\u00e9ho po\u010das\u00ed panely dodaly „dost“ energie, a t\u00edm \u017ee nem\u00e1m zat\u00edm dokonfigurovan\u00e9 chov\u00e1n\u00ed elektr\u00e1rny p\u0159i vybit\u00ed, a nem\u011bl jsem mo\u017enost b\u00fdt doma p\u0159i „dojezdu“ baterie k n\u011bjak\u00fdm 5-10%, musel jsem test ukon\u010dit na SOC 23%.
