    Rectifier Huawei R4850G2 48V 42~58V 3000w

    Want to charge a 48V battery, when enough sun(pv) is here, when sun is weak Stop charging(maybe switch off AC?) till next day, when sun is strong enough start charging again. So is it ok that this Rectifier is connected always to battery? And also a pv charger parallel to the Huawei?

    Are there revisions of R4850 or r4875 which incompatible with this mod? Is it ok, to always connect the Huawei to the battery? Anyone optimized the Fan to cool more and be more silent?
