Peak Power Solar now supplies three different Sacred Sun battery chemistries in Nepal, giving each project a chemistry matched to its site rather than a one-size-fits-all default.
Industrial gel battery (GFMJ series). This is Sacred Sun’s original, longest-proven industrial line, using GEL-state electrolyte rather than free liquid acid. The gel design prevents leakage and stratification, tolerates a wide temperature range, and has a long service life under the EUROBAT classification — which is why it’s still our default recommendation for telecom, power system, and larger stationary energy storage installations where the bank sits in a fixed location for its whole service life.
Industrial lead-carbon battery (DCS series). The newer addition to the lineup. Lead-carbon batteries blend carbon material into the negative plate, which reduces sulphation and significantly improves charge acceptance in partial-state-of-charge use — exactly the daily charge/discharge pattern a solar-charged battery bank sees. Sacred Sun rates the DCS series for 3,000+ cycles at 70% depth of discharge, well beyond a standard flooded or AGM lead-acid battery, while still using familiar lead-acid installation and maintenance practices.
Lithium battery in rack-mount modules. For sites that want the smallest footprint and lowest weight per kWh, Sacred Sun’s rack-mounted LiFePO4 modules install into standard 19″ racking, with a built-in BMS handling cell balancing, protection, and monitoring over CAN or RS485. Multiple modules wire in parallel (up to 48 units) to scale capacity without the floor space a comparable lead-acid bank would need. See the Sacred Sun lithium battery product page for full specifications.
Which of the three makes sense for a given project depends on the site: available space, budget, expected cycling pattern, and how the bank needs to be installed. Get in touch with Peak Power and we’ll help match the right Sacred Sun battery chemistry to your system.
