Check out battleborn 100a lifepo4 batts.
10 year guarantee.
Cannot be damaged from lv depletion.
Zero mtce
Much smaller and much lighter.
One 100ah lifepo4 is effectively equal in storage to two T105 trojans
BB batts can be discharged at 100% without damage
T105s can be discharged to 50% without damage
Reduced recharging times (especially handy with gen set recharge. Batts will accept whatever your inverter is capable of charging at. 50% charge rate. 100a lifepo4 charges at 50a rate. Greatly reduces genset recharge time).
Battleborn is a US company with superior support.

$850 Battleborne (10 year warranty) vs $320 T105 (18 month warranty) with more than twice the life expectancy and 10 years minimum of trouble free operation.

Your inverter must have the capability to charge at 14.4 volts (typically a custom setting)
Older inverters can many times be upgraded to this capability with new board and controller (i.e. Magnum board $220 and Magnum ARC controller $230).
My 2 cents

This after my $550 per AGMs no good after about two years. Eight bad batts...No warranty protection.
