For a full guide on setting up your solar energy storage system, head over to our blog.
At WattCycle, we build our lithium batteries using highest quality materials for long-lasting performance. Designed to get the most out of your solar setup, they’re ready for both on-grid and off-grid use. And with zero maintenance required, you can count on steady power—no check, no fuss, just energy independence on your terms.
A solar on-grid system, also known as a grid-tied solar system, is linked to both the solar panels and the main grid. This means you can draw power from your panels or the grid, and you can also automatically send excess solar power to the grid.
An off-grid solar system is a solar panel system that has no connection to the utility grid at all. This means that all of your system's power comes from the panels, so you don't need to rely on an external power source. You can meet your energy needs entirely through solar power and stored batteries.
A hybrid solar system is a system that uses the combination and integration of solar power with a backup power source (usually a generator or the main grid) and battery storage to generate electricity.
Array Sizing: Aim for a PV array capacity 1.2–1.5× your lithium battery bank’s watt-hour rating to replenish daily depth of discharge.
Charge Controller Settings: Set bulk/absorption voltage to 14.4 V (for 12 V systems) and float to 13.6 V; enable temperature compensation if available.
Seasonal Adjustments: In low-sun months, reduce discharge depth to 40 %–50 % and consider shifting absorption time longer; in high-sun seasons, you can safely utilize up to 80 % DOD for maximum yield.

Tento blogový príspevok je podrobnou recenziou batérií Watt Cycle 314Ah Mini LiFePO4 od majiteľa plachetnice, ktorý sa pripravuje na plavbu cez Atlantik. Autor prešiel z batériovej banky AGM s kapacitou 440Ah na systém LiFePO4 s kapacitou 628Ah s použitím dvoch batérií Watt Cycle zapojených paralelne.
Tento blogový príspevok vysvetľuje kľúčové rozdiely medzi batériami s hlbokým cyklom a batériami s dvojitým účelom so zameraním na ich použitie v obytných automobiloch. Batérie s hlbokým cyklom: Sú navrhnuté tak, aby poskytovali stabilný a konzistentný zdroj energie počas dlhého obdobia. Sú ideálne na prevádzku spotrebičov, ako sú chladničky, vodné čerpadlá a svetlá, keď ste bez napájania z elektrickej siete. Kľúčovou vlastnosťou je ich schopnosť hlboko vybiť sa (až na 80 – 90 % ich kapacity) bez poškodenia. Dvojúčelové batérie: Tieto batérie, známe aj ako štartovacie batérie, sú navrhnuté tak, aby dodávali silný impulz energie na naštartovanie motora. Hoci môžu napájať aj niektoré príslušenstvo, v podstate sú kompromisom medzi štartovacou batériou a batériou s hlbokým cyklom. Článok odporúča hlboko cyklické batérie pre tých, ktorí trávia veľa času mimo siete a majú vysoké nároky na energiu pre svoje spotrebiče. Dvojúčelové batérie sú vhodnejšie na kratšie cesty s častým štartovaním motora a nižšou spotrebou energie pre príslušenstvo. Príspevok tiež zdôrazňuje výhody batérií LiFePO4 (lítium-železitý fosfát), ktoré sú ľahké, majú dlhšiu životnosť a nevyžadujú údržbu v porovnaní s tradičnými olovenými alebo AGM batériami.
