Description
A solar plant rarely brings the battery to full charge, and ordinary lead cells quickly sulfate in this mode. The carbon additive in RE technology is designed specifically for PSoC, so at 50 % DoD the life reaches 3800 cycles (data for 25 °C). In standby mode the service life is up to 20 years, so the same cells are also suitable for backup. The 2 V format makes it possible to build a battery for any inverter voltage, and the large capacity of a single cell removes the need for parallel strings. The cells are sealed, use VRLA-AGM technology, comply with IEC 60896-21/22 and hold UL 1973 (MH66728) and UL 1989 (MH14533) certificates.
How to choose
Capacity is chosen by the daily energy and the permissible depth of discharge, and the number of cells in a string by the inverter voltage. A deeper discharge of 70 % gives more energy every day, but the life falls to 2700 cycles against 3800 at 50 %. If you need a ready cabinet with a pre-assembled string, the same line includes a cabinet system based on these cells with a mounting kit. For small stand-alone sites at 12 V, XTV-WT monoblocks are more suitable.

FAQ
How many cycles does the RE lead-carbon cell withstand?
2700 cycles at 70 % DoD and 3800 cycles at 50 % DoD at a temperature of 25 °C.
What is PSoC mode for a solar plant battery?
It is operation in a partially charged state, when the battery does not reach 100 % charge for days. RE cells are designed specifically for this mode.
What capacity do RE 2 V cells have?
From 1200 to 1700 Ah per 2 V cell.
How long do RE cells last in standby mode?
Up to 20 years in standby mode; with cycling, the life is determined by the number of cycles completed.
What standards do RE cells meet?
IEC 60896-21/22, as well as UL 1973 (MH66728) and UL 1989 (MH14533) certificates.
